xwin-xdg-menu shouldn't be doing anything to the environment, and 
especially not based on if it's running a terminal...

If you're starting it from the start menu item, it inherits the 
environment from the login shell which that uses to run startxwin, and 
the processes it starts inherit that environment in turn.

The behaviour of bash in this area is complex (see the section 
"INVOCATION" in the man page), but I suspect that any other 
non-interactive shells in the ancestry of the mc process won't have run 
startup scripts. So, if you've made a change to bash startup files, 
you'd need to restart xwin-xdg-menu to see a change.
