bug#22238: 25.0.50; isearch symbol search can't find ,@symbol

[Michael Heerdegen <michael_heerdegen@web.de>]

Hello,

isearch's symbol search (M-s _) doesn't find symbols as in

  ,@symbol

when searching for "symbol".  This was already the case in Emacs 24.5.

Regexp searching for "\_<" stops at the "@" char (not at the "s").  At
least, `isearch-forward-symbol' seems to behave as documented, dunno
about the "\_<" regexp.

Anyway, the behavior is not good.  People use to replace symbols with
isearch's symbol search when they have renamed a function or variable.
Missing occurrences can introduce bugs.


Thanks for your help,

Michael.
