annotate roundup/rest.py @ 5740:abbea26a11df

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Clean up pylint reports of unused modules, duplicate imports, indent issues, relative import, extra ';', unneeded pass. Also added support for TypeError as I restructured accept header parsing a bit to remove uneeded "version" variable assignments
