i18n: extract strings with xgettext
The xgettext program knows about Python string formatting and will
mark messages with a special "#, python-format" comment in the hg.pot
file. When msgfmt compiles the file, it can check these messages to
ensure that the translated string uses the same conversion specifiers
as the original string.
The pygettext program is still used to extract the docstrings.
