Diff & Symlinks

[Frank Mitchell]

Diff with Symlinks happens to be very convenient for me. The implementation
is probably a consequence of how some standard Unix Systems Command works.
But obviously it would be an idea to switch it off by default, while leaving
the user with the existing option.

Another issue would be getting Recursive diff to work for Non-Root users
without being needlessly obstructed by Permissions.

I do not know what is the historical reason for program "diff" to follow

proper  implementation.

So, we need to either disable recursive diff to follow the symlink, or
we need a switch (option) to enable following symlink feature in recursive
comparison of diff when a user real needs it.
