When you press the key bound to cycle the tabs CTRL-PageDown by default say and
you have MiscCycleTabs=FALSE and you are at the last tab already then it
outputs characters to the terminal ";5~"
It would be nice if it suppressed such output.
(this was bug 3624 but I had it under xfce4-terminal not Terminal)
Benedikt, did you have any comments on this?
Fixed in commit 47ddbb38da0030ebc279e61b6a2414448d32126e.
