Deduce exec_path also from calls to git with a relative path

Browse Source 
There is already logic in the git wrapper to deduce the exec_path from
argv[0], when the git wrapper was called with an absolute path.  Extend
that logic to handle relative paths as well.

For example, when you call "../../hello/world/git", it will not turn
"../../hello/world" into an absolute path, and use that.

Initial implementation by Scott R Parish.
