Description Christian Persch 2014-05-28 11:39:50 UTC 
Could short-circuit changing e.g. window-title, icon-title, current-{file,directory}-uri etc when the new string is the same as the old one.
Comment 1 Egmont Koblinger 2014-05-28 12:08:10 UTC 
Signals are batched up so only one is sent, even if multiple changes to the same value occur in a very short time.

Short circuiting can happen in vteseq.c:vte_sequence_handler_set_title_internal() and friends, in that case a quick back-n-forth toggling will still emit the signal; or in vte.c:vte_terminal_emit_pending_signals() in which case it won't.
