    emulation: Swallow urxvt OSC 777
    
    Accept OSC 777 but make it a no-op.
    
    Some distros patch their vte downstream with the rejected patch from
    bug 711059, which leads to problems with these escape sequences being
    shown on the terminal when using an unpatched upstream build of vte
    but the system-installed patched vte.sh script, due to vte not
    ignoring unknown escape sequences (bug 403130).
