Autoload with absolute path fails

[Marlon Richert <marlon.richert@xxxxxxxxx>]

Hi, all!

According to the [autoload documentation](http://zsh.sourceforge.net/Doc/Release/Shell-Builtin-Commands.html#index-autoload), one should be able to pass it an absolute path:

> If _name_ consists of an absolute path, the function is defined to load from the file given (searching as usual for dump files in the given location).

However, I have a user reporting this to fail: https://github.com/marlonrichert/zsh-edit/issues/1

What could cause this to happen? It works fine for me and we are both on Zsh 5.8.

Cheers,
