Csh behaves differently on some SysV systems.  AIX doesn't source
.cshrc on an su.  This causes me no end of annoyance and confusion
when I maintain workstations whose users insist on making root's
default shell csh (yes, I know how to fix this with an alias).

AIX also will refuse a login if the user does not own his/her
.cshrc, .login, or .profile.
