[Quilt-dev] handling empty new files

[jerome lacoste]

I am having problems to generate a patch with a new empty file.

Here's a test case that exhibits the problem in quilt.
The message "Nothing in patch test.diff" is was gets printed instead
of "Refreshed..."

        $ mkdir -p d/patches
        $ cd d

        $ quilt new test.diff
        > Patch test.diff is now on top
        $ quilt add file.txt
        > File file.txt added to patch test.diff
        $ touch file.txt
        $ quilt refresh
        > Refreshed patch test.diff

        # $ quilt diff 

        $ cd ..
        $ rm -rf d

The problem lies in the inability for diff to generate a diff for new
empty files (used in diff_file in patchfns):

rm file.txt
touch file.txt
diff /dev/null file.txt

produces nothing.

Any idea?
