I was thinking of merging things as follows:
- Keep your changes, except that instead of pushing (t . FUN)
onto the load history, we add the autoload data to the
`autoload' symbol property.
- Instead of using Vautoload_queue, we rely on the `autoload'
symbol property and the load-history in un_autoload (which
is also used by Frequire).
That would also be a good step towards merging un_autoload
and unload-feature.
