patch: changing math space size

[Eran Tromer]

In current 1.2.0cvs it's no longer possible to increase the size of
spaces in mathed using 
  C-<space> <space> <space> ...

<space> immediately after C-<space> is interpreted as usual, i.e., a
mathcursor->pop() is executed.

The attached patch seems to fix this.
