=for ref 

Expand a compactified path into a dir list

You supply a pathlist and leading '+' and '~' characters get expanded into
full directories.  Normally you don't want to use this -- it's internal to the
autoloader -- but some utilities, like the online documentation searcher, need
to be able to use it.
