vi eats control-Ds in sourced files

[Chris Torek]

Index:	ucb/ex/ex_get.c 4.3BSD Fix

Description:
	When vi (ex) reads .exrc files or other sourced files, it
	discards control-D.  This makes it difficult to map something
	to a string that includes a control-D, or to remap ^D itself.

Repeat-By:
	Create a .exrc file with the line

		map! ^D foo

	(that is, map control-D anything).  Run vi; note `missing rhs'
	error.

Fix:
	This seems to be what is required.  In any case it accounts
	for the fact that newline-to-control-D mapping is done only
	when `intty' is set.
