I actually think keeping "char c" as in the original is a lot more
logical for that particular case, as the existing use of that local
variable are _all_ about C's 'char', and not about a very short
unsigned integer.  The variable is compared with C's character
constants like ' ' (whitespace) and '\t' (horizontal tab), or is
given to XDL_ISSPACE() macro, which is also about C's character.

But because it is so minor a thing, I do not think that it deserves
a reroll on its own.  Just in case if there are other things that
need to change and the series needs a reroll, here is the only
change required for this.
