searchpath problems

[John M. Sellens]

For the past several years, accounts created on MFCF machines and/or
those created with the mkusers command have been provided with
.cshrc/.login/.profile files that use searchpath and that call
read_system_news.  These files also contain a warning that they
shouldn't be changed before reading the relevant man page, which
explains why searchpath and read_system_news are important.
