I know it's a freeze, but this is bugfix update of a minor package with restarted upstream.

- update to 3.7
* bug fix in timezone handling (thanks to Chris Rorvick).
* major performance gain in the CVS client code (thanks to
Sergei Trofimovich).
* third field in an author entry is now interpreted as if it
were TZ.
* remove the --test-log option now that cvsps has its own test suite.
* new --reposurgeon option for passing reference-lifting hints
to reposurgeon.
