ed: add support for -s command-line option as mandated by POSIX
...
Apart from the -p option, POSIX also mandates an -s option which
suppresses the output of byte counts for the e, E, r, and w command.
From these commands, Busybox ed presently only implements the r and w
commands. This commit ensures that these two command do not output any
bytes counts when the -s option is passed. The shell escape command,
also effected by the -s option, is not implemented by Busybox at the
moment.
