Subject: Numbers with specific base (was: [PATCH] userdiff: remove empty subexpression from elixir regex)
Date: Fri, 13 Dec 2019 21:59:13 +0100	[thread overview]
Message-ID: <87tv64ymam.fsf@Rainer.invalid> (raw)

Nothing to do with the patch from Ed, but the regex following his
correction matches a lot of things that decidedly are not "Numbers with
specific bases" as it claims to do in the comment.

Here, things like "+0bad" would match as a base 2 number, which doesn't
seem right.  If it's intended to match that broadly, I'd have expected a
comment to that effect.  Maybe something like


or (if the resulting group is not a problem someplace else)


to more specifically match only what the comment says?
