I've tried to implement some kind of "SHAREDIR search path" as we've
discussed on another thread [1] but it shows out that we need some
considerable refactoring to make it work.
Talking with Peter privately IIUC we concluded that we may document
this limitation that using extension control path with an extension that
uses a custom "directory" field on .control file will not work. I think
that we may add a note section on "extension_control_path" doc on [2],
what do you think?
