lowercase prompts The prompts are interactive and not meant for scripts.

lowercase ui.debug and assert output This does not effect the log or status commands and should be okay according to the compatibility rules.

lowercase help output Changes docstrings to begin with a lowercase word. Only docstrings used in help output is changed. Scripts are not expected to grep the output of 'hg help' so this change should pose no problem with regard to the compatibility rules.

test: added testcase for cvsps log message lookahead

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.

convert/gnuarch: add cat-log payload to commit description

bisect: improve hg bisect -c (relative paths, error handling) hg bisect -c failed with a relative path or when the executable wasn't found. Use util.find_exe()+os.spawnl() instead of os.spawnlp() and improve the handling of errors (killed process, exe not found). Thanks to Georg Brandl for reporting it.
