There is nothing more annoying than su'ing to root and discovering that
even simple things like md5 and ping aren't in your path.  This patch
moves the custom root-path setting from .login to .cshrc, so that users
who su to root get a decent (and consistent) path.  An appeal to change
/etc/login.conf to provide a decent path for all users seems to have been
vetoed for the time being.  As a result, users will still, by default,
not find ping or md5 in their path.  However, at least root gets a decent
default now.
