I agree it could be done later, but it would be great if you could
follow-up with that. Right now if you do:
a = !git b
b = !git a
You end up with a fork bomb, and we don't guard against this, and if you
have mixed execution / internal aliasing, e.g.:
a = b
b = c
c = d
d = !git a
The loop detection doesn't kick in.
It should be easy to add detection for this on top. See what we do with
git_config_push_parameter() in git.c already, i.e. you'd add some
simliar env variable, set items in the string list delimited by
e.g. whitespace, and then just pre-populate your string list with that
if it's set, and re-set it & carry it forward.
Then any combination of internal aliasing and custom commands will
benefit from loop detection.
