I hadn't thought of anything, I just thought you might know of another
way you liked better.

The man page and squid.conf still talk about a '-a port' command line
option to override the port number, even though it is gone from the
code. Because of that former option, I chose '-A fd' as the option. So
'-A 0' would work for passing in stdin. If you like, I could make it
only work via stdin, but I don't think it makes sense to support both a
general file descriptor option and a separate one for stdin-only. Let
me know which way you prefer. Oh, or are you saying that squid should
check to see if stdin is a socket (with getsockopt), and if so assume it
should just use it?
