with xterm, patch #281 defaults to vt420 level.
 
actually #280, but there was a regression fixed in #281:
     * change  default  emulation  level  to VT420 (discussion with Ailin
       Nemui).

While working on #280, I compared results with vttest for Reflection
and PowerTerm.  Reflection agrees with xterm (except if it is set
to "xterm" emulation...), and PowerTerm is missing a few aspects.

no (nor given its development history for the past 6-7 years, is any
significant change in vte's capabilities for terminal emulation likely).

See
        http://invisible-island.net/xterm/xterm.faq.html#compare_versions

for instance.

Aside from DECTCEM, I don't recall any feature that vte implements which
comes from a higher emulation level than vt220.
