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.

Checking this again and: this seems to be fixed.  Closing.

Not sure about the obscure case involving a symbol @foo as mentioned by
Andreas, but searching for such a symbol works using symbol isearch, and
,@foo is read as (,@ foo) by the Lisp reader, not as (, @foo), and
isearch doesn't need to match a symbol @foo here, so I guess everything
works at least relatively well.

Michael.
