    composetable: Don't abort on unsupported escape sequences
    
    People might put all sorts of gunk in their .XCompose file, in
    the hope that XLib makes sense of it. Even if we don't make sense
    of it, we shouldn't abort, but instead ignore the lines we can't
    understand. Pointed out in
