Re: using non-Emacs regexp syntax

    Is there a function to convert non-Emacs regexps (e.g. "ab(c+|d)" to
    Emacs regexps (example to "ab\(c+\|d\)")?

The first form appears to be an "extended regexp" or egrep-style regexp.
The second appears to be a "basic regexp" or grep-style regexp.

This conversion feature in Lisp would be useful to add after the release.
