cvslog 1.51

This is a minor bug fix release, the most important fix being proper flushing of the mail file handle so that forking diffstat or cvs doesn't sometimes result in a doubled message. It also cleans up some warnings when parsing malformed CVS passwd files.

I have some more changes pending (cleaning up wrapping the list of changed files), but they're currently waiting on me to decide whether I want to rewrite the option and configuration file parsing along the lines of the new code in svnlog.

You can get the latest version from the cvslog distribution page.
