[Chicken-users] chicken-install should use sudo -v

[John Cowan]

Currently when you install an egg with many dependencies using the -s
(sudo) switch, you have to wait to enter your password until the first
time chicken-install invokes sudo.  If, on detecting the -s switch,
chicken-install immediately ran "sudo -v", the password would be requested
at the top.  This variant of sudo does not run any command.

Older sudo's that don't understand -v will just report an error, and no
harm done.

You may well have to log in to particular machines, hunt down   address@hidden
people who still have processes running, and kill them."
