Sorry, I think I have misled you.

In gtags/global I cannot think of any reason to distinguish
symbolic links from hard links.  I thought perhaps you had
some reason and that was why it currently does so.

More generally, the only circumstances I can think of are
where one needs exclusive access to the file (writing/
locking), or wants information on the filesystem storage
(e.g. ls -l) or needs to interface to a tool which does not
treat symbolic links as files (e.g. our source control system
- perforce).

There is an argument for following symbolic links, and treating
the link target as the true file, but my preference is for this to be
a selectable option, especially with tools which open files for
reading only.  I like tools by default to treat symbolic links in the
same way as hard links and files, or behave as if they had done so.

When do you want to distinguish symbolic link and hard link?
In other words, when is it useful?
