/*
* @@@ logic isn't quite complete yet. It should go something like this:
*
* - if there is no related item,
* - try file,
* - if there is a colon, try VCS,
* - give up
* - if there is a related item,
* - if it is a VCS,
* - try the revision matching or predating (if different repo) that of the
* related repo,
( - fall through and try as if it was a file
* - try opening as file. If this fails,
* - if the name of the file to open is absolute, give up
* - try `dirname related`/file_ope_open
* - give up
*
* @@@ should we see if non-VCS file is in a VCS ? E.g.,
* /home/my-libs/foo.lib 1234:/home/my-project/foo.sch
* or maybe use : as indictor for VCS, i.e.,
* :/home/my-libs/foo.lib ...
*
* @@@ explicit revision should always win over related.
