top: refactored some of that 'other filtering' support

If we are to support preserving 'other filter' entries
in the rcfile, then the current logic setting up those
osel entries for a WIN_t must be shareable for startup
and when interacting with a user. So, this commit just
repositions this current code in a shareable function.

[ along the way, we give the prior guy a proper name ]
