issue 178: refined git command cwd setting.

Sebastien Devaux created 6 years ago

For unknown reason setting .git as current directory for the called
git command fails when git-bug is called from a git hook (and it was
observed only in this case). Forcing use of current dir when the
repo path is ".git" restore the expected behavior.
