[PATCH 1/3] filter: introduce cgit_open_email_filter() wrapper

[Jason A. Smith]

From: John Keeping <john at keeping.me.uk>

We provide email addresses to the email filter surrounded by angle
brackets, but we will soon remove these in our internal representation.
Introduce a wrapper so that we only have to add them in one place.
