Hi,


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).


Regards,

Murdo
