If all you were doing was reading from stdin, then it probably would
be that easy. Wanting readline to work correctly requires a bit more
work; and don't forget that there are escape sequences that should
*not* be uppercased (as they'll change in meaning). So yeah, it's a
bit esoteric... but I'm glad it's working.
