No, this is a separate problem. POSIX says getopts shall end option processing
when it encounters either an error or a non-optarg consisting of '--' or not
beginning with '-'. zsh's getopts has no way of disabling '+'-prefixed option
handling, so it isn't conformant with that.

Regarding the other thing, Peter's patch from 35318 was applied, but mine was
not. I guess Peter wanted me to change the behaviour only with POSIX_BUILTINS
set. I'll look at it again later
