bug#15920: 24.3; [PATCH] etags doesn't recognize functions with [<=>] in them.

[Oleh]

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
