From f26d1ba6b01a358c83f28219c7a01e546e84d2ee Mon Sep 17 00:00:00 2001

Subject: Add features associated with autoloading a function using an absolute
 path.

-d defaults to normal fpath

-r remembers the path without actually loading.  May be combined with -d.

-R does the same but it's an error if not found

-X can now take a directory path: this is used to output not yet loaded
functions that have an associated path.
