PATCH: edit-command-line: disable `monitor' option locally

[Frank Terbeck <ft@bewatermyfriend.org>]

I was just told, that suspending an editor while using
`edit-command-line' will cause the command line to be lost, yielding
this:

edit-command-line:zle:17: widgets can only be called when ZLE is active

Which makes sense.

I first thought to disable suspending by disabling the appropriate
shortcut via `stty'. But that doesn't work if the editor suspends anyway
when it sees a "C-z" byte (vim does).

So, in order to shield users from accidential dataloss, this patch
unsets the `monitor' option temporarily. That does the trick for me and
I don't think there is anything this would break.

If I'm missing something, yell.
