So USE_EXPAND $Editor and use the flags to figure out what the default 
editor should be.  Or just set EDITOR so that when fcron builds it finds 
the editor you used.  You can always emerge fcron with EDITOR=nano and 
then unmerge nano and claim fcron is 'broken'.  I think most people 
wouldn't care though.

The only problem currently is that EDITOR is set in /etc/profile (not 
/etc/profile.env) so if you use sudo to emerge fcron, EDITOR will get 
stripped from the environment, causing this problem.  Then again I'd say 
thats a sudo configuration problem, not necessarily a build problem.
