commit 80e6f6251e96dd7b8a9ab0fdbf63b03a73ef6692
Author: Guy Harris <guy@alum.mit.edu>
Date:   Sun Oct 19 23:14:50 2014 -0700

    Get rid of calls to ctype.h functions.

    They don't handle values outside the range -1 to 127, and their behavior
    is locale-dependent.  Use g_ascii_isXXX() and g_ascii_toXXX() instead of
    isXXX() and toXXX().

    If you're checking for printable ASCII, don't use isascii() and don't
    use iscntrl(), use g_ascii_isprint().  If you're checking for graphical
    ASCII, i.e. printable ASCII except for a space, use g_ascii_isgraph().

    Use ws_xton() to convert a hex digit character to the corresponding
    numeric value.
