extdiff: wrap long lines in docstring and comments Gettext wraps lines in the messages when it writes them to the hg.pot file and that makes long lines look odd in the resulting .po file.

extdiff: prevent exception on double-translation The docstring is translated twice: once when used as a format string, and once on display. The second translation fails when the first translation introduces non-ASCII characters in the string. The problem is that the gettext module calls unicode(message) on the string, i.e., it decodes it to a Unicode string using the ASCII encoding (the default encoding). By translating it into a Unicode string here, the unicode() call becomes a noop.
