Avoid duplicate table look ups.

Avoid duplicate table look ups.

These two spots both are matching 'c+' where 'c' is some character
against a Unicode table.  Prior to this patch, if it matched a single
'c', it would fall into a while loop, where it matches that same 'c'
again.  Simply increment the pointer past the first match, and the while loop
will start looking for succeeding matches starting with the next
character in the input.
