windows: disable pager when packaged with py2exe...

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.
