Howdy hackers,
I'm seeing erratic behaviour when using zparseopts together with GNU
long options which have additional dashes and the first part before the
dash is common. Example:
---clip---
#!/bin/zsh
zparseopts -E -D -- -gnu:=gnu -gnu-tard:=gnutard
print -- $gnu\\n$gnutard
---clap---
Executing as intended:
% ./test.zsh --gnu argh --gnu-tard rms
--gnu argh
--gnu-tard rms
Executing with imaginary new option:
% ./test.zsh --gnu argh --gnu-tard rms --gnu-tard-added-even-longer-opt whyohwhy
--gnu argh
--gnu-tard -added-even-longer-opt

Well, you've told zparseopts that --gnu-tard is an option that takes a
mandatory argument, and you have not told zparseopts that
--gnu-tard-add... is an option, and the argument of an option is
allowed to appear in the same word as the option itself (so that -a2
is the same as -a 2), so zparseopts believes -add... is the argument
of the option you told it about.

Makes sense, but also makes it impossible to use zparseopts with a
caller that may spontaneously add options and expect scripts to work
unmodified.
