Ali Mohammad Pur 4ede121d31 Shell: Add support for regex match patterns
We previously allowed globs as match pattern, but for more complex
matching needs, it's nice to have regular expressions.
And as the existing "name a part of the match" concept maps nicely to
named capture groups, we can simply reuse the same code and make groups
with names available in the match body.
