Synopsis: which(1) ought to append @ if result is symlink

State-Changed-Why: 
This is a very dangerous addition to the output.

Normally which(1) is used to determine if there is a program file
with that name in the users $PATH, to know if the program is there
and know the full path. By adding this character, suddenly the
program file returned doesn't exist anymore despite that the program
file does exist.

I'm sorry but this shouldn't be done.
