Good point, this was with the latest devel branch, though the behavior can
be seen in the release version for the privileged, verbose and xtrace
options. The change was in [1].

The propblem is that SHELLOPTS was only being (partially) reset somewhat by
accident, since the functions that handle `posix' and `ignoreeof' options
hapen to call set_shell_opts. (Prior to the change above, the posix mode
code would do this unconditionally but now it does only when the value did
actually change).

The diff below should do the trick.
