2021-12-29ed: add support for -s command-line option as mandated by POSIXSören Tempel
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. function old new delta packed_usage 34096 34115 +19 doCommands 1887 1900 +13 readLines 388 397 +9 .rodata 104196 104200 +4 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 45/0) Total: 45 bytes Signed-off-by: Sören Tempel <soeren+git@soeren-tempel.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
