diff mercurial/cmdutil.py @ 37603:678d760c71ff

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
export: extract function to write patch to file object (API) This is common use case of cmdutil.export(), and we wouldn't want to handle formatter thingy everywhere. .. api:: The ``fp`` argument is removed from ``cmdutil.export()``. Use ``cmdutil.exportfile()`` instead.
