Re: RegExp in Find Definition

[Pavel Nedev]

Sorry, one mistake:

for use case 3) "global -dx .tags"

I would actually expect to get no results at all as ".tags" as I understand it 
should filter only definitions that start with any valid char for identifier 
('_', 'a'-'z',... etc.) and ending with "tags". For example:

gtags, htags, _tags are valid
rxtags, tags, gtags_new are not valid.

Best Regards,
Pavel
