Log Message:
Fixed the wording of the <ctype.h> character classification functions by
always using "function" instead of "macro".

Changed "undefined result" into "undefined behavior" for argument values
outside the valid range. Since the character table is allocated via
malloc(), it _may_ happen that it starts at a page boundary, so that
negative values for the argument result in a segmentation fault. In that
case, there is no result at all.
