Add two configration variables grep.extendedRegexp and grep.lineNumbers to
allow the user to skip typing -E and -n on the command line, respectively.
Scripts that are meant to be used by random users and/or in random
repositories now have use -G and/or --no-line-number options as
appropriately to override the settings in the repository or user's
~/.gitconfig settings. Just because the script didn't say "git grep -n" no
longer guarantees that the output from the command will not have line
numbers.

Last night I had to make these two emergency reverts, but now we have a
better understanding of which part of the topic was broken, let's get rid
of the revert to fix it correctly.

The fetch-pack/upload-pack protocol relies on the underlying transport
(local pipe or TCP socket) to have enough slack to allow one window worth
of data in flight without blocking the writer. Traditionally we always
relied on being able to have two windows of 32 "have"s in flight (roughly
3k bytes) to stream.
The recent "progressive-stride" change allows "fetch-pack" to send up to
1024 "have"s without reading any response from "upload-pack". The
outgoing pipe of "upload-pack" can be clogged with many ACK and NAK that
are unread, while "fetch-pack" is still stuffing its outgoing pipe with
more "have"s, leading to a deadlock.
Revert the change unless we are in stateless rpc (aka smart-http) mode, as
using a large window full of "have"s is still a good way to help reduce
the number of back-and-forth, and there is no buffering issue there (it is
strictly "ping-pong" without an overlap).

When 'no-done' protocol extension is used, the upload-pack (i.e. the
server side) process stops listening to the fetch-pack after issuing the
final NAK, and starts sending the generated pack data back, but there may
be more "have" send by the latter in flight that the fetch-pack is
expecting to be responded with ACK/NAK. This will typically result in a
deadlock (both will block on write that the other end never reads) or
SIGPIPE on the fetch-pack end (upload-pack will finish writing a small
pack and goes away).
Disable it unless fetch-pack is running under smart-http, where there is
no such streaming issue.

When we merge into an unborn branch, there are basically two
steps:
1. Write the sha1 of the new commit into the ref pointed
to by HEAD.
2. Update the index with the new content, and check it out
to the working tree.
We currently do them in this order. However, (2) is the step
that is much more likely to fail, since it can be blocked by
things like untracked working tree files. When it does, the
merge fails and we are left with an empty index but an
updated HEAD.
This patch switches the order, so that a failure in updating
the index leaves us unchanged. Of course, a failure in
updating the ref now leaves us with an updated index and
mis-matched HEAD. That is arguably not much better, but it
is probably less likely to actually happen.

"git merge" without specifying any commit is a no-op by default.
A new option merge.defaultupstream can be set to true to cause such an
invocation of the command to merge the upstream branches configured for
the current branch by using their last observed values stored in their
remote tracking branches.

Introduce --min-parents and --max-parents options which limit the
revisions to those commits which have at least (or at most) that many
commits, where negative arguments for --max-parents= denote infinity
(i.e. no upper limit).
In particular:
--max-parents=1 is the same as --no-merges;
--min-parents=2 is the same as --merges;
--max-parents=0 shows only roots; and
--min-parents=3 shows only octopus merges
Using --min-parents=n and --max-parents=m with n>m gives you what you ask
for (i.e. nothing) for obvious reasons, just like when you give --merges
(show only merge commits) and --no-merges (show only non-merge commits) at
the same time.
Also, introduce --no-min-parents and --no-max-parents to do the obvious
thing for convenience.
We compute the number of parents only when we limit by that, so there
is no performance impact when there are no limiters.

Start the initial request small by halving the INITIAL_FLUSH (we will try
to stay one window ahead of the server, so we would end up giving twice as
many "have" in flight at the very beginning). We may want to tweak these
values even more, taking MTU into account.

The "git fetch" client presents the most recent 32 commits it has to the
server and gives a chance to the server to say "ok, we heard enough", and
continues reporting what it has in chunks of 32 commits, digging its
history down to older commits.
Move the hardcoded size of the handshake window outside the code, so that
we can tweak it more easily.

When orphaning a commit on a detached HEAD, the warning
currently looks like:
Warning: you are leaving 3 commits behind, not connected to
any of your branches:
- commit subject 1
- commit subject 2
- commit subject 3
If you want to keep them by creating a new branch, this
may be a good time to do so with:
git branch new_branch_name 933a615ab0bc566dcfd8c01ec8af159f770d3fe5
Instead of using the "-" list, let's provide a more
traditional oneline format, with the abbreviated sha1 before
each subject. Users are accustomed to seeing commits in this
format, and having the sha1 of each commit can be useful if
you want to cherry-pick instead of creating a new branch.
The new format looks like:
Warning: you are leaving 3 commits behind, not connected to
any of your branches:
933a615 commit subject 1
824fcde commit subject 2
fa49b1a commit subject 3

When leaving a detached HEAD, we do a revision walk to make
sure the commit we are leaving isn't being orphaned.
However, this leaves crufty marks in the commit objects
which can confuse later walkers, like the one in
stat_tracking_info.
Let's clean up after ourselves to prevent this conflict.

The receiving end of "git push" advertises the objects that the repository
itself does not use, but are at the tips of refs in other repositories
whose object databases are used as alternates for it. This helps it avoid
having to receive (and the pusher having to send) objects that are already
available to the receiving repository via the alternates mechanism.
Tweak the helper function that implements this feature, and move it to
transport.[ch] for future reuse by other programs.
The additional test demonstrates how this optimization is helping "git push",
and "git fetch" is ignorant about it.
