Question about uid check in csh's source command

[Roy Smith]

	I am trying to figure out a way to make csh read a system-wide
.login file before reading $HOME/.login.  Looking at the source for csh
(/usr/src/bin/csh/sh.c) it seems all you have to do is just add one line
to the startup code.  Where it says:

	if (loginsh) {
		srccat(value("home"), "/.login");
	}

I guess I should just be able to add another call to srccat to read in
/usr/lib/csh.login or something like that.  Reading a bit further into the
code you find out that srccat won't source a file unless it has the same
uid or gid as you do.  This I don't understand; why should it care?
