Hmm, I thought Functions/Complete/_main_complete was the main
completion function.  Where is it?

As far as restoring it, Do'h!  I thought I tested that, but obviously 
not.  Is there an easy way to bind a function to a different name and
restore it?  I've tried games with stuff like foo=$(functions TRAPZERR) 
... eval $foo, but that seems suboptimal.

You can do

zsh% eval newname "$(functions oldname)"
zsh% oldname() { ...  }
zsh% eval oldname "$(functions newname)"
zsh% unfunction newname

as long as newname is unique and oldname isn't awaiting autoload.

For traps, if you use the "trap" builtin instead of a TRAPxxx() function,
the trap is automatically removed at the end of the local scope.  That
does not restore any outer-scope traps, though (global-scope TRAPxxx() is
deleted by local-scope "trap ... xxx" commands).

Possibly so, but it ought to be done on entry into the main completion
function and undone again before returning.

PATCH: zsh-3.1.5-pws-9, TRAPZERR fix for new completion

[Matt Armstrong]

We probably want to defeat TRAPZERR within the new
completion stuff.  Mine just prints "That didn't work",
which isn't desirable during completion.

I'm not sure about the other special functions.
