Thanks for compiling the rest.

-    printf(_("  --NAME=VALUE       set run-time parameter\n"));
+    printf(_("  --NAME=VALUE       set run-time parameter, a shorter form of -c\n"));

This part with cross-references in the output is still meh to me, for
same reason as for the doc changes I've argued to discard upthread.

         write_stderr("%s does not know where to find the server configuration file.\n"
-                     "You must specify the --config-file or -D invocation "
+                     "You must specify the --config-file (or equivalent -c) or -D invocation "

I can fall behind changing this one, still I'm not sure if this
proposal is the optimal choice.  Adding this option to --help makes
sense when applied to this error message, but that's incomplete in
regard with the other GUCs where this concept applies.  A different
approach would be to do nothing in --help and change the reference of
--config-file to -c config_name=VALUE, which would be in line with
--help.
