8a2222286c backport ERE interval/repetition expressions from Apple awk-24
The lack of POSIX interval expressions[*] (a.k.a. bounds, a.k.a.
repetition expressions) in regular expressions is listed under BUGS
in 'awk.1'. Apple's version of onetrueawk has supported these since
at least 2009, judging by the date stamp on their src/b.c in:
https://opensource.apple.com/tarballs/awk/awk-24.tar.gz

A bug report prompted NetBSD to swiftly integrate this code into
their awk. This commit is based on that NetBSD diff.

b.c:
- Backport POSIX-standard interval expressions support in regular
  expressions via NetBSD from Apple awk-24 (20070501).

main.c:
- Bump version ID.

FIXES:
- Add note and credit for this feature.

awk.1: section BUGS:
- Remove line saying interval expressions are not supported.
