typing: mark the argument to mercurial.i18n.gettext() non-Optional
Few if any of the callers are handling a `None` return, which is making pytype
complain. I tried adding @overload definitions to indicate the bytes -> bytes
and None -> None relationship, but pytype doesn't seem to apply that to `_()`
through the function assignment. What did work was to change `_()` into its own
function that called `gettext()`, but that has an extra function call overhead.
Even putting that function into an `if pycompat.TYPE_CHECKING` block and leaving
the existing assignments in the `else` block caused pytype to lose track of the
@overloads.
At that point, I simply gave up. PyCharm doesn't like that it can return None,
given the new type hints, but pytype doesn't complain about this nor does it
see any callers passing None. The most important thing here is to catch str
being passed anyway.

Mercurial ========= Mercurial is a fast, easy to use, distributed revision control tool for software developers. Basic install:: $ make # see install targets $ make install # do a system-wide install $ hg debuginstall # sanity-check setup $ hg # see help Running without installing:: $ make local # build for inplace usage $ ./hg --version # should show the latest version See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information. Notes for packagers =================== Mercurial ships a copy of the python-zstandard sources. This is used to provide support for zstd compression and decompression functionality. The module is not intended to be replaced by the plain python-zstandard nor is it intended to use a system zstd library. Patches can result in hard to diagnose errors and are explicitly discouraged as unsupported configuration.
