Fair enough. _wanted_yet would possibly address your second point above
but not the first. It would be nice though if we can find some names
which better express the difference between _wanted and _requested. I
can't though and the current names aren't too bad.

I agree that it shouldn't look like the version tags. I'd try to use
something which makes it clear that the tag is set before the move -
something like old-comp-dirs or pre-comp-mv. I've never dealt with cvs
tags though so am probably not the best person to answer this.
> Builtins/_popd Zsh/Command
_popd could possibly be something like Zsh/Type/_directory_stack as
that is all it completes and it is called by _cd. It might make _cd
more readable and would adapt better to changes in popd's usage.
The script looks fine though I've not looked in as much detail as
Other than the naming of _compalso, _wanted, _requested, _next_label,
_all_labels and the cvs tag are there any other outstanding issues on

Yes. Unless the parent process exported FPATH to zsh. At the least, we
should change zsh so that if FPATH is set in the environment when it
starts, the completion directories are added to it instead of replacing

I always thought of them as just examples and user contributions as
opposed to being part of zsh's functionality. Before the new
completion, they had to be manually installed and added to $fpath. I've
just noticed though that they are now mentioned in the documentation
which I suppose makes them more official.

As I said with the original suggestion, there could be a variable set
to point to the base of the installed functions. I don't understand why
compinit would need to know before-hand what directories it should add -
it would just use a bit of globbing modified for $OSTYPE and options
passed to it, I'd be very much against any manufacturing of compinit,
especially while it is installed below /usr/local/share.

The ARGC test thing is clever. Do we need to account for kshautoload
though? How does someone with kshautoload set get the new completion
system to work short of doing unsetopt kshautoload? Having tried a few
ideas, I can't think of any better ways to detect when source is in
