It appears that cscope uses its own (rather old) egrep implementation and it does not support a lot of now widely available extended regular expression character classes like \w or \< \> (word boundary). It would be great if cscope's internal egrep implementation were updated to something more modern.

Alternatively, it would be at least good to have an option to use external egrep program (even though this would probably lead to poor performance).
