libbb: new option FEATURE_ETC_SERVICES: if off, /etc/services reads often avoided
In practice, "wget http://host.com/" always uses port 80. People explicitly set non-standard ports via options or parameters ("telnet 1.2.3.4 567" or "telnet 1.2.3.4 ftp") instead of modifying /etc/services. function old new delta telnet_main 1466 1464 -2 rdate_main 215 198 -17 fakeidentd_main 269 252 -17 parse_url 459 392 -67 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-103) Total: -103 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
