[PATCH] init: don't reset ZLE_RPROMPT_INDENT on term init

[dana <dana@xxxxxxx>]

currently, rprompt_indent gets reset to 1 whenever the terminal is
re-initialised, so if the user ever touches TERM, even locally in a
function or in a pre-command assignment before a built-in, it will
revert their ZLE_RPROMPT_INDENT

imo we should leave it alone if the user has explicitly set it
