[PATCH] Already running a command (& subshell prompt?)

[Leonard den Ottolander <leonard den ottolander nl>]

Hi,

Removing the odd code executed on Ctrl-o in invoke_subshell() the
"Already running a command" issue on C-o, tab, tab, n, C-o, <command>
seems to be fixed. But maybe there are other scenarios in which it can
be reproduced.

I totally got rid of the subshell state ACTIVE as it is unused except in
the removed code snippet. I didn't quite get the three state logic
anyway. Maybe the author wanted to indicate a difference between "panel
view" and "panels hidden view"?

Does this perhaps also fix the subshell prompt issue? See the comment /*
Hack to make prompt reappear */ in the removed code.

Leonard.
