chpldoc: Don’t emit a space after foo.type
[contributed by @cassella, reviewed by Lydia]

The space results in output like

… function:: proc <=>(ref lhs: owned, ref rhs: lhs.type )

and

… method:: proc init=(other: heap(this.type .eltType))

Update three .good files.

Passed a full paratest with futures.
