Now that we have proper documentation for --force's interaction with -d
and -m, we can avoid duplication and consider -M and -D as convenience
aliases for -m --force and -d --force.

In the common case that the commit encoding matches the
output encoding, we do not touch the buffer at all, which
makes things much more efficient. But it might be unclear to
a consumer that we will pass through bogus sequences.

It's better to start the man page with a description of what
submodules actually are, instead of saying what they are not.
Reorder the paragraphs such that
- the first short paragraph introduces the submodule concept,
- the second paragraph highlights the usage of the submodule command,
- the third paragraph giving background information, and finally
- the fourth paragraph discusing alternatives such as subtrees and
remotes, which we don't want to be confused with.
This ordering deepens the knowledge on submodules with each paragraph.
First the basic questions like "How/what" will be answered, while the
underlying concepts will be taught at a later time.
Making sure it is not confused with subtrees and remotes is not really
enhancing knowledge of submodules itself, but rather painting the big
picture of git concepts, so you could also argue to have it as the second
paragraph. Personally I think this may confuse readers, specially
newcomers though.
Additionally to reordering the paragraphs, they have been slightly
reworded.

'merge.branchdesc' is only mentioned in the docs of 'git fmt-merge-msg'.
The description of 'merge.log' is already duplicated between
'merge-config.txt' and 'git-fmt-merge-msg.txt'; instead of duplicating the
description of another config variable, extract the descriptions of both
of these variables from 'git-fmt-merge-msg.txt' into a separate file and
include it there and in 'merge-config.txt'.
Leave 'merge.summary' only in git-fmt-merge-msg.txt, as it is marked
as deprecated.

When http-backend spawns "upload-pack" to do ref
negotiation, it streams the http request body to
upload-pack, who then streams the http response back to the
client as it reads. In theory, git can go full-duplex; the
client can consume our response while it is still sending
the request. In practice, however, HTTP is a half-duplex
protocol. Even if our client is ready to read and write
simultaneously, we may have other HTTP infrastructure in the
way, including the webserver that spawns our CGI, or any
intermediate proxies.
In at least one documented case[1], this leads to deadlock
when trying a fetch over http. What happens is basically:
1. Apache proxies the request to the CGI, http-backend.
2. http-backend gzip-inflates the data and sends
the result to upload-pack.
3. upload-pack acts on the data and generates output over
the pipe back to Apache. Apache isn't reading because
it's busy writing (step 1).
This works fine most of the time, because the upload-pack
output ends up in a system pipe buffer, and Apache reads
it as soon as it finishes writing. But if both the request
and the response exceed the system pipe buffer size, then we
deadlock (Apache blocks writing to http-backend,
http-backend blocks writing to upload-pack, and upload-pack
blocks writing to Apache).
We need to break the deadlock by spooling either the input
or the output. In this case, it's ideal to spool the input,
because Apache does not start reading either stdout _or_
stderr until we have consumed all of the input. So until we
do so, we cannot even get an error message out to the
client.
The solution is fairly straight-forward: we read the request
body into an in-memory buffer in http-backend, freeing up
Apache, and then feed the data ourselves to upload-pack. But
there are a few important things to note:
1. We limit the in-memory buffer to prevent an obvious
denial-of-service attack. This is a new hard limit on
requests, but it's unlikely to come into play. The
default value is 10MB, which covers even the ridiculous
100,000-ref negotation in the included test (that
actually caps out just over 5MB). But it's configurable
on the off chance that you don't mind spending some
extra memory to make even ridiculous requests work.
2. We must take care only to buffer when we have to. For
pushes, the incoming packfile may be of arbitrary
size, and we should connect the input directly to
receive-pack. There's no deadlock problem here, though,
because we do not produce any output until the whole
packfile has been read.
For upload-pack's initial ref advertisement, we
similarly do not need to buffer. Even though we may
generate a lot of output, there is no request body at
all (i.e., it is a GET, not a POST).

Fix remaining instances where "pack-file" is used instead of
"packfile". Some places remain where we still use "pack-file",
This is the case when we explicitly refer to a file with a
".pack" extension as opposed to a data source providing a pack
data stream.
