function: lx_chomp_ws()
USAGE:
void lx_chomp_ws(lx_s *s)
Remove all ending whitespace characters from string buffer s.
Whitespace characters include spaces (' '), tabs ('\t'),
newlines ('\n'), and carriage returns ('\r').
This is done by modifying s->len. lx_chomp_ws() does not
deallocate or overwrite any memory used by s.
