For example, if I use xfrun4 with "man mutt", it doesn't work because the "mutt"
arguments it not passed to the Terminal. xfrun4 executes xfterm4 -e man mutt
which does not work.

Suggested fix:

Reproducible: Always

1. xfrun4
2. man mutt
3. [x] run in terminal
4. ENTER

man is executed and the Terminal immediately closes

Expected Results:  
'man mutt' should be executed and the Terminal schould close if the user closes it.
