Hello

1)
i looked at allopt() and while doing that i noticed that it would not give
correct results for some options. notable e.g. monitor and zle.

Here i get:
% builtin set -o
.
.
monitor on
.
.
zle on

but then:
% builtin set -o | command grep -E '(\<monitor\>|\<zle\>)'
monitor off
zle off

>From that I guess that Zsh resets some specific options when used in
pipes/command substitutions.
The attached allopt() works around that.

Additionally:
This version makes it possible to throw s.th. like '_H-uP' or 'NO__H-uP' at
allopt and does not hardcode length of options when printing.
KUDOS for that goes to pws: http://zsh.sourceforge.net/Guide/zshguide05.html


2)
While working on the above i noticed that 'builtin set -o' and '${options}' are
not equal. The later knows some more. See attached missing_options for a list.
This makes me wonder if that is intended.


Any comments are welcome.



kind regards,

Thilo
