No, I mean have a builtin with an explicit test that tells the user if
the terminal supports the feature or not.  Then changing the terminal
and deciding whether to set a zero right-prompt indent can be done
entirely in shell code.

TERM=mymmodernpowerfulterminalemulator
if builtin-decides-the-terminal-supports-non-destructive-move-left
  ZLE_RPROMPT_INDENT=0
else
  ZLE_RPROMPT_INDENT=1
fi

Is anything likely to happen before I release 5.0.4?  I was planning to
produce it imminently, but maybe we don't want to disappoint the punters
with a half implemented feature.
