Patch for switching to subshel in editor and viewer

[Walery Studennikov <despair sama ru>]

Hello.

Here is the patch which allows to switch to subshell
from internal viewer (Ctrl-O) and from internal editor
(Ctrl-Shift-O, because Ctrl-O is already taken by another function).

view.c.diff		- viewer stuff.
edit_key_translator.c	- edutor stuff
mc.1.in.diff		- documentation patch


I hope this patch will be included into CVS.


Regards, Walery
