Hello!

I want to compare 'configure.in' from the master branch with 'configure.ac' from the gpm-2-dev branch.

What I tried:

% git-diff master..gpm-2-dev configure.ac fatal: ambiguous argument 'configure.ac': unknown revision or path not in the working tree. Use '--' to separate paths from revisions

# ok, correct, there is no configure.ac in master # But not what I want.

% git-diff master..gpm-2-dev configure.in

# shows that the file does not exist in gpm-2-dev. Correct. # But not what I want.

Strange ist: % git-diff --summary master...gpm-2-dev and % git-diff --stat master...gpm-2-dev do not show the rename.

But using

% git log -Sconfigure gpm-2-dev

I find the rename in commit 5fe49d36d775af47c08bb9a0c0beabef609bba20.

Now I could do

% git-checkout master configure.in

in the gpm-2-dev branch and manually compare it with diff. But - you guessed it - is not what I want.

I really think git can do that, but currently I do not see the right way. So any idea on how to do that?

Sincerly

Nico
