Determines whether a character is a white-space character.
Unlike the standard C library isspace() function, this only
recognizes standard ASCII white-space and ignores the locale,
returning FALSE for all non-ASCII characters. Also, unlike
the standard library function, this takes a char,
not an int, so don't call it on EOF, but no need to
cast to guchar before passing a possibly non-ASCII character in.
