[issue2064] firstpara template filter

[David Hull]

New submission from David Hull <hull at snap.com>:

It would be nice to have a template filter that returns the first paragraph
of a string for filtering summary messages.  Attached is a patch that adds this.

Longer justification: I've converted a code base from CVS to mercurial,
where the commit messages did not use the summary-on-the-first-line
mercurial convention.  Generally the first paragraph summarizes the change,
and the rest of the commit message gives more details.  It would be nice to
be able to specify a template so that the "hg log" output would return just
the first paragraph of each commit message.
