Re: git alias question

[Michael Horowitz <michael.horowitz@ieee.org>]

The log operation does seem to make the most sense as the mechanism to
search for the results.  Making it work with difftool would work...
Not sure if "--log" to difftool or some other options as suggested in
the other thread would be most consistent UI-wise as stated, but
either would work for me.

On a separate note, some environment variable like GIT_PREFIX with the
CWD would make the alias functionality more flexible.
