If removing a space character changes the behavior, please file a bug 
report. Spaces are ignored in gcode, except within a comment.

Come to think of it, there is another case where removing a space 
character should change the behavior. If the original line was too long 
and removing the space makes the line a legal length, the old program 
was illegal and the new one is legal. I don't think that is what is 
happening here.
