Re: [PATCH 03/19] completion: use __gitdir() in _git_log()

SZEDER Gábor [off-list ref] writes:

The standard way to find out the path to the repository in the
completion script is the __gitdir() helper function, because that
handles the repository path given on the command line (i.e. git
--git-dir=/path/to/repo log --<TAB>).  However, there is one
exception: the completion function for 'git log' still uses 'git
rev-parse --git-dir' directly, and could offer (or not) the '--merge'
option erroneously when the repository is specified on the command
line.

Here `--merge` is the visible symptom, and the real issue you fixed is
that it used to be looking into a repository that is different from the
user is working with, right [*1*]?

Well spotted, and the fix sounds correct.

Thanks.

*1* I am just making sure I am reading the above right; I am not
suggesting to omit description of visible symptom at all---quite
the opposite, I do want to see these visible symptom descriptions
in the log messages.
