Well, if git-gui is designed to interoperate with CLI git (and I think
that is a sensible thing to aim for), we probably should revisit the list
of hooks in hooks.txt and make sure we define the environment these hooks
are invoked in precisely enough (this incidentally will help C rewrite
effort to avoid regressing).  Then, hooks that take input from and give
output to the user could be launched with I/O redirected to talk with wish
(which I presume has a terminal lookalike widget you can embed in your
application).
