    emulation: Swallow iterm2 OSC 1337
    
    Accept OSC 1337 but make it a no-op.
    
    When sshing to an osx host the iterm2 integration may be active,
    causing the remote shell to emit iterm2 OSC 1337 sequences that
    clutter the vte terminal since we don't ignore unknown sequences
    (bug 403130).
