[PATCH 2/3] vcs_info git: In interactive rebases, properly support the full form of the "exec" verb.

[Daniel Shahaf <danielsh@apache.org>]

The code before this commit happened to have done the right thing:
"exec" lines were handled by the catchall forward compatibility case,
which happened to have had virtually the same effect as the correct
case.  However, that was merely an accidental result.  This patch makes
the code do the right thing deliberately, rather than by accident.
