While comparing this with OpenBSD (ie: trying to figure out what mkstemps()

Browse source 
is good for... :-)), I discovered that part of the change when mkstemps()
was brought in was missed - it was missing the termination case to make
sure it doesn't walk into the suffix.  This isn't the same code OpenBSD
has, I think this is a little better as we terminate the loop in a better
spot.
