In particular on Windows, where shell scripts are even more expensive
than on MacOSX or Linux, it makes sense to move a loop that forks
Git at least once for every line in the todo list into a builtin.
Note: The original code did not try to skip unnecessary picks of root
commits but punts instead (probably --root was not considered common
enough of a use case to bother optimizing). We do the same, for now.

These tests were a bit anal about the *exact* warning/error message
printed by git rebase. But those messages are intended for the *end
user*, therefore it does not make sense to test so rigidly for the
*exact* wording.
In the following, we will reimplement the missing commits check in
the sequencer, with slightly different words.
So let's just test for the parts in the warning/error message that
we *really* care about, nothing more, nothing less.

This is crucial to improve performance on Windows, as the speed is now
mostly dominated by the SHA-1 transformation (because it spawns a new
rev-parse process for *every* line, and spawning processes is pretty
slow from Git for Windows' MSYS2 Bash).

To avoid problems with short SHA-1s that become non-unique during the
rebase, we rewrite the todo script with short/long SHA-1s before and
after letting the user edit the script. Since SHA-1s are not intuitive
for humans, rebase -i also provides the onelines (commit message
subjects) in the script, purely for the user's convenience.
It is very possible to generate a todo script via different means than
rebase -i and then to let rebase -i run with it; In this case, these
onelines are not required.
And this is where the expand/collapse machinery has a bug: it *expects*
that oneline, and failing to find one reuses the previous SHA-1 as
"oneline".
It was most likely an oversight, and made implementation in the (quite
limiting) shell script language less convoluted. However, we are about
to reimplement performance-critical parts in C (and due to spawning a
git.exe process for every single line of the todo script, the
expansion/collapsing of the SHA-1s *is* performance-hampering on
Windows), therefore let's fix this bug to make cross-validation with the
C version of that functionality possible.

The commands used to be indented, and it is nice to look at, but when we
transform the SHA-1s, the indentation is removed. So let's do away with it.
For the moment, at least: when we will use the upcoming rebase--helper
to transform the SHA-1s, we *will* keep the indentation and can
reintroduce it. Yet, to be able to validate the rebase--helper against
the output of the current shell script version, we need to remove the
extra indentation.

The first step of an interactive rebase is to generate the so-called "todo
script", to be stored in the state directory as "git-rebase-todo" and to
be edited by the user.
Originally, we adjusted the output of `git log <options>` using a simple
sed script. Over the course of the years, the code became more
complicated. We now use shell scripting to edit the output of `git log`
conditionally, depending whether to keep "empty" commits (i.e. commits
that do not change any files).
On platforms where shell scripting is not native, this can be a serious
drag. And it opens the door for incompatibilities between platforms when
it comes to shell scripting or to Unix-y commands.
Let's just re-implement the todo script generation in plain C, using the
revision machinery directly.
This is substantially faster, improving the speed relative to the
shell script version of the interactive rebase from 2x to 3x on Windows.
Note that the rearrange_squash() function in git-rebase--interactive
relied on the fact that we set the "format" variable to the config setting
rebase.instructionFormat. Relying on a side effect like this is no good,
hence we explicitly perform that assignment (possibly again) in
rearrange_squash().

An upcoming patch will move the todo list generation into the
rebase--helper. An early version of that patch regressed on an empty
rebase.instructionFormat value (the shell version could not discern
between an empty one and a non-existing one, but the C version used the
empty one as if that was intended to skip the oneline from the `pick
<hash>` lines).
Let's verify that this still works as before.

We started using our own timestamp_t type and PRItime format
specifier to go along with it, so that we can later change the
underlying type and output format more easily, but this does not
play well with gettext tools.
Because gettext tools need to keep the *.po file portable across
platforms, they have to special-case the format specifiers like
PRIuMAX that are known types in inttypes.h, instead of letting CPP
handle strings like
"%" PRIuMAX " seconds ago"
as an ordinary string concatenation. They fundamentally cannot do
the same for our own custom type/format.
Given that po/git.pot needs to be generated only once every release
and by only one person, i.e. the l10n coordinator, let's update the
Makefile rule to generate po/git.pot so that gettext tools are run
on a munged set of sources in which all mentions of PRItime are
replaced with PRIuMAX, which is what we happen to use right now.
This way, developers do not have to care that PRItime does not play
well with gettext, and translators do not have to care that we use
our own PRItime.
The credit for the idea to munge the source files goes to Dscho.
Possible bugs are mine.

The paragraph that describes the 'scissors' cleanup mode of
'commit' had the 'cut-line' in the middle of a sentence. This
made it possible for the line to get wrapped on smaler windows.
This shouldn't be the case as it makes it hard for the user to
understand the structure of the cut-line.
Reformat the pragraph to make the 'cut-line' stand on a line of
it's own thus distinguishing it from the rest of the paragraph.
This further prevents it from getting wrapped to some extent.

On Cygwin, similar to Windows, "git push //server/share/repository"
ought to mean a repository on a network share that can be accessed
locally, but this did not work correctly due to stripping the double
slashes at the beginning.
This may need to be heavily tested before it gets unleashed to the
wild, as the change is at a fairly low-level code and would affect
not just the code to decide if the push destination is local. There
may be unexpected fallouts in the path normalization.

config keys are compared, the case does not matter.
