I find that this sequence (.cshrc first, then .login) is the opposite of what
I want.  That is because I want to set up environment variables just once --
in .login, -- and I want them to be usable from .cshrc in each shell I use,
including the login shell.

So, I just reverse them:

.login (abbridged):

	setenv EDITOR /usr/local/bin/mg
	unset autologout
	set prompt="%m"; setenv SHOSTNAME $prompt
	biff y
	setenv HAVELOGGEDIN yes
	source ~/.tcshrc

.tcshrc (abbridged):

	if (${?HAVELOGGEDIN}) then
	  source ~/.customrc
	  set prompt="`whoami`@${SHOSTNAME}> "
	  set history=50 savehist=20
	endif

This way, when the login shell starts up, .tcshrc skips itself (because
HAVELOGGEDIN is not defined), .login is run, and it runs .tcshrc when it's
finished. 

On subsequent shells, just the .tcshrc is run, and it executes normally.
