Ah, the good old days!  I even modified 'make install' to copy the
completion script to /etc/bash_completion.d/.  And I was happy.

Don't know what is appropriate, and it's not documented.  I for one
copy it manually to ~/.git-prompt.sh every once in a while.  And I'm
not all that happy with that.

Not sure about the "sh" part.  The prompt function is very
Bash-specific, it won't work under a plain POSIX shell.

Do other VCSes have similar prompt scripts?  Where do they install
