When checking out another ref, the reflogs already record from which
branch you switched.  Do that also when switching to a detached HEAD.

While at it, record also when coming _from_ a detached HEAD.

The old way of fixing warnings did not succeed on MinGW.  MinGW
does not support C99 printf format strings for size_t [1].  But
gcc on MinGW issues warnings if C99 printf format is not used.
Hence, the old stragegy to avoid warnings fails.

This commits passes arguments of type size_t through a tiny
helper functions that casts to the type expected by the format
string.

The helper functions 'map' and 'skip_commit' were provided to commit
filters by sourcing filter-branch itself.  This was done with a certain
environment variable set to indicate that only the functions should be
defined, and the script should return then.

This was really hacky, and it did not work all that well, since the
full path to git-filter-branch was not known at all times.

Avoid that by putting the functions into a variable, and eval'ing
that variable.  The commit filter gets these functions by prepending
the variable to the specified commands.

When colors are set to "true" on the repository, the git log output
will contain control characters to set/reset the colors, even when
the output is to a pipe. This makes list_stash() fail as the
downstream sed does not see what it is expecting.

When you cherry-pick or revert a commit, naming it with an annotated
tag, we added a comment, attempting to repeat what we got from the end
user, to the message.

But this was inconsistent.  When we got "cherry-pick branch", we
recorded the object name (40-letter SHA-1) without saying anything like
"original was 'branch'".  There was no need to.  Also recent rewrite to
use parse-options made it impossible to parrot the original command line
without "unparsing".

This removes the code that implements the misguided "we dereferenced the
tag so record that in the commit message" behaviour.

When you have a file called HEAD in the work tree, the code to report
where the HEAD is at when "git checkout $commit^0" is done triggered
unnecessary ambiguity checking.

Explicitly mark the command line with "--" and make it clear that we are
talking about a revision.

When creating a bundle, symbolic refs used to be resolved to the
non-symbolic refs they point to before being written to the list
of contained refs.  I.e. "git bundle create a1.bundle HEAD master"
would show something like

388afe7881b33102fada216dd07806728773c011        refs/heads/master
388afe7881b33102fada216dd07806728773c011        refs/heads/master

instead of

388afe7881b33102fada216dd07806728773c011        HEAD
388afe7881b33102fada216dd07806728773c011        refs/heads/master

Introduce a special handling so that the symbolic refs are listed
with the names passed on the command line.
