cvsps: cvs log loop uses lookahead to avoid misleading text

Changes cvsps.py's cvs log reader to use a one-line lookahead, so
that possibly misleading log messages can be disambiguated.  In
particular I have past committers who used cvs log's 28-character
row of hyphens within commit messages; this throws cvsps and disrupts
conversion.  The only alternative in this case is to edit the cvs
,v file by hand, which bloodies mercurial's "don't change history"
principle.

Or use cvs admin -m.
