win32: meld from 3.18.1 installer does nothing on pressing F1 or selecting Meld->contents menu
1. Bug ~"5. Installer"
The title is self-desribing. The problem appears only for meld installed from installer, not for meld executed from checkout with pygobject-win32 binaries.
The reason is "combined":
- handling of meld.conf.UNINSTALLED* flags
- absence of gspawn-win32-helper.exe
