[Message part 1 (text/plain, inline)]

Hi all,

While functions with name like `string=' or `string>' are present in
TAGS generated by etags, `etags-tags-completion-table' doesn't recognize
them.  It's fixed by a tweak in the regex it uses. I attach the patch.

regards,
Oleh

I'm unable to reproduce this bug on the current trunk, so this may have
been fixed in the meantime.  I'm closing this bug report, but please
reopen if this is still a problem.
