Earlier, we tried to find the git commands in several possible exec
dirs. Now, if all of these failed, try to find the git command in
PATH.
This allows you to install the git programs somewhere else than
originally specified when building git, as long as you add that location
to the PATH.
Initial implementation by Scott R Parish.

Ah, right. I missed that one ;-)
How about this instead?
