ed: Don't undo commands in sigint

If newcmd is 0 then error() undo all the modifications
that happened since the last command, but this is  not
what POSIX mandates:

SIGINT	The ed utility shall interrupt its current activity, write the
	string "?\n" to standard output, and return to command mode
	(see the EXTENDED DESCRIPTION section).
