452202c74b sequencer: stop releasing the strbuf in write_message()
Nothing in the name "write_message()" suggests that the function
releases the strbuf passed to it. So let's release the strbuf in the
caller instead.

0009426d67 sequencer: support cleaning up commit messages
The run_git_commit() function already knows how to amend commits, and
with this new option, it can also clean up commit messages (i.e. strip
out commented lines). This is needed to implement rebase -i's 'fixup'
and 'squash' commands as sequencer commands.

a1c757623c sequencer: allow editing the commit message on a case-by-case basis
In the upcoming commits, we will implement more and more of rebase -i's
functionality inside the sequencer. One particular feature of the
commands to come is that some of them allow editing the commit message
while others don't, i.e. we cannot define in the replay_opts whether the
commit message should be edited or not.

Let's add a new parameter to the run_git_commit() function. Previously,
it was the duty of the caller to ensure that the opts->edit setting
indicates whether to let the user edit the commit message or not,
indicating that it is an "all or nothing" setting, i.e. that the
sequencer wants to let the user edit *all* commit message, or none at
all. In the upcoming rebase -i mode, it will depend on the particular
command that is currently executed, though.

1dfc84e9e0 sequencer: introduce a helper to read files written by scripts
As we are slowly teaching the sequencer to perform the hard work for
the interactive rebase, we need to read files that were written by
shell scripts.

These files typically contain a single line and are invariably ended
by a line feed (and possibly a carriage return before that). Let's use
a helper to read such files and to remove the line ending.

b5a670452c sequencer: prepare for rebase -i's commit functionality
In interactive rebases, we commit a little bit differently than the
sequencer did so far: we heed the "author-script", the "message" and the
"amend" files in the .git/rebase-merge/ subdirectory.

Likewise, we may want to edit the commit message *even* when providing a
file containing the suggested commit message. Therefore we change the
code to not even provide a default message when we do not want any, and
to call the editor explicitly.

Also, in "interactive rebase" mode we want to skip reading the options
in the state directory of the cherry-pick/revert commands.

Finally, as interactive rebase's GPG settings are configured differently
from how cherry-pick (and therefore sequencer) handles them, we will
leave support for that to the next commit.

c22f7dfb0c sequencer: remember the onelines when parsing the todo file
The `git-rebase-todo` file contains a list of commands. Most of those
commands have the form

	<verb> <sha1> <oneline>

The <oneline> is displayed primarily for the user's convenience, as
rebase -i really interprets only the <verb> <sha1> part. However, there
are *some* places in interactive rebase where the <oneline> is used to
display messages, e.g. for reporting at which commit we stopped.

So let's just remember it when parsing the todo file; we keep a copy of
the entire todo file anyway (to write out the new `done` and
`git-rebase-todo` file just before processing each command), so all we
need to do is remember the begin offsets and lengths.

As we will have to parse and remember the command-line for `exec` commands
later, we do not call the field "oneline" but rather "arg" (and will reuse
that for exec's command-line).

2863584f5c sequencer: get rid of the subcommand field
The subcommands are used exactly once, at the very beginning of
sequencer_pick_revisions(), to determine what to do. This is an
unnecessary level of indirection: we can simply call the correct
function to begin with. So let's do that.

While at it, ensure that the subcommands return an error code so that
they do not have to die() all over the place (bad practice for library
functions...).

6307041dd2 sequencer: strip CR from the todo script
It is not unheard of that editors on Windows write CR/LF even if the
file originally had only LF. This is particularly awkward for exec lines
of a rebase -i todo sheet. Take for example the insn "exec echo": The
shell script parser splits at the LF and leaves the CR attached to
"echo", which leads to the unknown command "echo\r".

Work around that by stripping CR when reading the todo commands, as we
already do for LF.

This happens to fix t9903.14 and .15 in MSYS1 environments (with the
rebase--helper patches based on this patch series): the todo script
constructed in such a setup contains CR/LF thanks to MSYS1 runtime's
cleverness.

Based on a report and a patch by Johannes Sixt.

004fefa754 sequencer: completely revamp the "todo" script parsing
When we came up with the "sequencer" idea, we really wanted to have
kind of a plumbing equivalent of the interactive rebase. Hence the
choice of words: the "todo" script, a "pick", etc.

However, when it came time to implement the entire shebang, somehow this
idea got lost and the sequencer was used as working horse for
cherry-pick and revert instead. So as not to interfere with the
interactive rebase, it even uses a separate directory to store its
state.

Furthermore, it also is stupidly strict about the "todo" script it
accepts: while it parses commands in a way that was *designed* to be
similar to the interactive rebase, it then goes on to *error out* if the
commands disagree with the overall action (cherry-pick or revert).

Finally, the sequencer code chose to deviate from the interactive rebase
code insofar that when it comes to writing the file with the remaining
commands, it *reformats* the "todo" script instead of just writing the
part of the parsed script that were not yet processed. This is not only
unnecessary churn, but might well lose information that is valuable to
the user (i.e. comments after the commands).

Let's just bite the bullet and rewrite the entire parser; the code now
becomes not only more elegant: it allows us to go on and teach the
sequencer how to parse *true* "todo" scripts as used by the interactive
rebase itself. In a way, the sequencer is about to grow up to do its
older brother's job. Better.

In particular, we choose to maintain the list of commands in an array
instead of a linked list: this is flexible enough to allow us later on to
even implement rebase -i's reordering of fixup!/squash! commits very
easily (and with a very nice speed bonus, at least on Windows).

While at it, do not stop at the first problem, but list *all* of the
problems. This will help the user when the sequencer will do `rebase
-i`'s work by allowing to address all issues in one go rather than going
back and forth until the todo list is valid.

03a4e260e2 sequencer: plug memory leaks for the option values
The sequencer is our attempt to lib-ify cherry-pick. Yet it behaves
like a one-shot command when it reads its configuration: memory is
allocated and released only when the command exits.

This is kind of okay for git-cherry-pick, which *is* a one-shot
command. All the work to make the sequencer its work horse was
done to allow using the functionality as a library function, though,
including proper clean-up after use.

To remedy that, take custody of the option values in question,
allocating and duping literal constants as needed and freeing them
at end.

82b83da8d3 pretty: avoid adding reset for %C(auto) if output is empty
We emit an escape sequence for resetting color and attribute for
%C(auto) to make sure automatic coloring is displayed as intended.
Stop doing that if the output strbuf is empty, i.e. when %C(auto)
appears at the start of the format string, because then there is no
need for a reset and we save a few bytes in the output.

26a7b23429 http: control GSSAPI credential delegation
Delegation of credentials is disabled by default in libcurl since
version 7.21.7 due to security vulnerability CVE-2011-2192. Which
makes troubles with GSS/kerberos authentication when delegation
of credentials is required. This can be changed with option
CURLOPT_GSSAPI_DELEGATION in libcurl with set expected parameter
since libcurl version 7.22.0.

This patch provides new configuration variable http.delegation
which corresponds to curl parameter "--delegation" (see man 1 curl).

The following values are supported:

* none (default).
* policy
* always
