A very small tarball showing this issue is at
http://www.veripool.org/attachments/download/703/test.tgz

To run this, using Emacs 24.3 (and 23.3 and probably others but not 25.0),
extract and type ./test.sh

You'll see the first four "new" keywords are highlighted. Later ones are
incorrectly not highlighted.

If you then edit test.el to change
v-font-long-name-here-here-here-here-face to v-font-short-face, which has
an identical definition, you'll see the fontification works correctly.
