With the terrible side effect of letting people think their
applications will just work, but introducing the very serious risk of
security problems, leading to, say:

gcc: dj:yourpassword:1234:567:DJ: invalid argument

instead of 

gcc: @/etc/passwd: invalid argument


Sure this is probably not so much of an issue for GCC (although remote
compile servers are not totally unheard of), but it could easily
become a very serious problem for other applications that might take
filenames from the network and worry about quoting - but not @; those
would then need fixing.
