[RFC/PATCH v2 8/8] completion: small optimization

[Felipe Contreras <felipe.contreras@gmail.com>]

No need to calculate a new $c with a space if we are not going to do
anything it with it.

There should be no functional changes, except that a word "foo " with no
suffixes can't be matched. But $cur cannot have a space at the end
anyway. So it's safe.

Based on the code from SZEDER Gábor.
