Pre-5.0.5 part 3: Heuristic for ZLE_RPROMPT_INDENT

[Bart Schaefer <schaefer@brasslantern.com>]

Another one we agreed to leave for after a stable release.  This takes a
best guess at whether the terminal can handle having a character written
to the lower right corner, and removes an unnecessary import from the
environment [it is already handled correctly by the generic environment
import in createparamtable()].
