[RESEND] [PATCH v3 1/1] commit-links.sh: improve regular expressions

[mailings at hupie.com (Ferry Huberts)]

From: Ferry Huberts <ferry.huberts at pelagic.nl>

The default length for sha1 abbreviations in git is 7.

A '#num' at the beginning of the commit message is now
recognised, a ':#num' as well, etc.: a '#num' anywhere
is now converted to a link.
