That's what it's supposed to do.  At least, it is supposed to reset all
configuration options -- it does not set the options relating to the
state of the shell, such as INTERACTIVE and PRIVILEGED.

You can't set NO_LOCAL_OPTIONS without fear in any case.  Your `simple
notation' is wrong -- you should set LOCAL_OPTIONS *after* setting
other options.  LOCAL_OPTIONS is tested when the function returns,
not when options are set.
