diff Lib/optparse.py @ 31858:0d8ee28bf6f0 legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix support for the "prog" keyword to the OptionParser constructor, as well as directly setting the .prog attribute (which should be supported based on the class docstring). Closes SF bug #850964.
