Hello,
With latest bzr-emacs:
- emacs -Q
- open "foo.c"
- turn on auto-fill (M-x auto-fill-mode)
- write the following comment:
--8<---------------cut here---------------start------------->8---
/*
#bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla
--8<---------------cut here---------------end--------------->8---
- result: auto-fill does not work here
In GNU Emacs 24.0.90.2 (x86_64-suse-linux-gnu, GTK+ Version 2.22.1)
of 2011-10-23 on micropit

Hello, Peter.
Thank you for taking the trouble to submit this bug report all these
years ago, and sorry it's taken so long to attend to it.
The problem was a simple coding error, checking for a macro before
checking whether or not we were in a comment. Your line of "#bla bla
...." was thus handled as a macro, and by the default setting of
`c-ignore-auto-file' didn't get filled.
I have now fixed this in the Emacs master branch, which will be getting
released as Emacs-30.1 maybe in a year's time. I'm closing the bug with
this post.
If you would like to try out the fix yourself, here is the patch, which
needs to be applied in directory lisp/progmodes in the Emacs source
tree.
