[OctDev] A fix for edit.m

[Per P. <per...@ma...>]

Hi,
on Mac OS X edit.m breaks when issuing 'edit' without any parameters.
The cause seems to be a difference in how whitespace is treated (on OS 
X spaces are allowed in file- & pathnames).
The [EDITOR %s] part comes out as 'emacs ' (trailing space) instead of 
'emacs'.

A potentital fix is pasted below. I don't have any other system to test 
it on so I won't commit it just yet.
