I tried this on both the latest AUCTeX release and some earlier 14.0.4
that was lying around.
The issue arose when using log-edit-generate-changelog-from-diff for a
commit involving tex files. I distilled it down to the above example.
It's clear what's happening -- reftex expects a master file, but it's a
non-file buffer. I don't know enough about style hooks to diagnose why
reftex is being called in this manner in this situation.
Any suggestions would be welcome.
Thanks, best,
Paul
