} That sounds reasonable.

OK, so various questions ...

Are we sticking with the name ZLE_RPROMPT_INDENT ?  None of the other
prompt-related variables have "ZLE_" stuck on the front of them, even
though a number of them are useless when zsh/zle is not loaded.

Is it OK to declare ZLE_RPROMPT_INDENT in params.c or should it go in a
Zle/*.c file?  zle_params.c is currently limited to parameters that are
pseudo-local to widget context so this would need special handling.

In the event that the terminal has no non-destructive move-left sequence,
should assigning ZLE_RPROMPT_INDENT=0 print a warning?  Should it also
(or instead) ignore the value and revert to 1 in that case?

I suppose it should also reset itself upon assignment to TERM.  This is
looking like a fairly large effort for a fairly tiny feature ...
