I'm unsure about that (vidputs is "supposed" to allow for this sort of case).

I was curious, and looked through VTE's git history, found that
it's recognized that code since the initial import in 2002/02/25.

https://git.gnome.org/browse/vte/tree/src/vte.c?id=38fb480261b192dd73a8edcd22599d0d2fe57f67#n1102

Whether it _works_ is hard to say (we could digress on that -- some
of the other codes such as blink and invisible have not worked in
any version of VTE).

I had an older "gnome" entry before VTE, and see that I "updated" it in
September 2003, but took a closer look in July 2004 in reference to

https://bugzilla.redhat.com/show_bug.cgi?id=122815

(probably the first sighting of VTE).  Some of those entries were
from RPMs (which means that they came from cut/paste), and some were
ones that I tested (and revised).  But an omission like this is easy
to do, if I'm not reading the source-code.

However, I can add it (will test against vte-2012, and probably
put the change there).
