Unmatched ". bug in csh

[SJOBRG.ANDY%MIT-OZ%mit-mc at sri-unix.UUCP]

The problem is the \n in the first setenv. It goes into the variable just
fine, but when EXINIT is expanded in the second setenv, the newline gets
expanded in with it...and csh is stupid about things like newlines without
'\'s before them. Even if you place extra '\' within the first setenv,
it STILL won't work. Csh loses over sh on things like this. Sigh.
