I've seen this as well... I have to C-g several times and quickly "move
off" the header line.

It doesn't happen when I use diff for code under cvs.  However, a
standalone .diff file in a directory where the file "test" doesn't exist
will happen everytime.

copy between the snips and save as /tmp/test.diff

Then open the file...

The modeline will continuously prompt for:
Use file Version: /tmp/test
