+	* 18278: Functions/TCP/tcp_output, Functions/TCP/tcp_spam,
+	Functions/TCP/zgprintf, Doc/Zsh/tcpsys.yo: zgprintf is already
+	implemented as zformat in the zsh/zutil module, so is unnecessary.
+
 	* unposted, see 18276: Completion/Unix/Command/_perforce:
 	fix labels and clients after `@'; rationalise function and tag
 	names; add date completion; add service=p4-<subcommand> support;
