windows: disable pager when packaged with py2exe
With Windows and py3, all output that got directed to the pager was lost. It
can be worked around by the user piping to `more`, but that's easy to forget,
and can be dangerous if `hg diff` or similar incorrectly shows no changes. The
problem appears to be the new WindowsConsoleIO in py3.6[1]. We've worked around
it with PyOxidizer by setting the `Py_LegacyWindowsStdioFlag` interpreter
option, and worked around it with `hg.bat` and `exewrapper.c` by internally
setting `PYTHONLEGACYWINDOWSSTDIO=1`.
Unfortunately, py2exe doesn't appear to be able to set the interpreter option,
and somehow seems to also ignore the environment variable. The latter isn't a
good fix anyway, since setting it in the environment would affect other python
programs too. We can't install a global config for this because a config closer
to the user (e.g. from before pager was turned on by default) can override it.
