Matthias has since written back to me again and says he's having all sorts
of problems with zcompile'd functions even after starting from scratch and
with ksh_autoload turned off.  So the issue of documenting the "correct"
way to use compsys with kshautoload is separate.

I don't specifically mean "does the above workaround deserve a FAQ entry"
but rather "does using compsys with kshautoload deserve a FAQ entry",
whatever the best A to the Q turns out to be.

The autoload method used isn't stored anywhere in the function structure.
Only the fact that the function is not yet defined is stored, and then zsh
applies whatever autoload setting is in effect globally at the time that
the function is loaded.

I suppose we could modify the storage and the code that does autoloading
[as opposed to modifying only bin_autoload()]; I forget why I didn't do
so at the time -- probably because it was a significantly larger change.

Please note that undefined functions don't actually have any function body
at all.  The "functions" command creates a dummy body when it outputs a
function that has no definition.  So it's not just a matter of changing
the dummy body.
