Re: git alias question

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.

FWIW, you can also do this as:
 ldiff = log -p -1 --format=format: --

ldifft = "!git difftool `git rev-list --reverse -n 2 HEAD -- $1` -- $1"

I don't know that you can do something equivalent with difftool. I
suppose you could do the above with "GIT_EXTERNAL_DIFF=<some difftool
wrapper> git ldiff", but that's not very helpful.

difftool cannot be driven by log right now.  It is something we
thought would be helpful in the past:

Perhaps we would want a convenient way for "log -p" or "show -p" to drive
difftool as a backend?

I think that's exactly it.  difftool wraps diff; a log equivalent
would be quite helpful.

One idea is for difftool to learn a "--log" option to make it wrap log
instead.  I don't know if a diff-like command having a "--log" option
is ideal from a consistency-of-user-interface POV so I'm open to
ideas.  It is convenient, though.  It does seem like difftool would be
a good place to expose this feature.

I'd be interested in the "teach log / show -p about GIT_EXTERNAL_DIFF"
route, if that sounds like a good idea.
