test-highlight: adapt output to latest pygments keeping backwards compatibility

issue1577: fix broken test by assuming less about CVS output. Specifically, output of "cvs ci" varies unpredictably across CVS versions, so any test that includes the output of "cvs ci" is doomed to fail some of the time. This fixes that by discarding the output of "cvs ci".

cvsps: make debugging easier by adding __repr__() methods.

cvsps: update docstring for changeset class.

manifest: improve error message about newlines in filenames Include the offending filenames in the error message. Now this error message is consistent with the same error issued by dirstate.py (although there is still duplicate code).

help texts: write command line switches as -a/--abc

Update qimport help explaining how to read a patch from stdin (Issue371)

convert: Improved svn source detection.
