Hello, thank you for the suggestion.

I dont' touch what '-n' option shows and rewrite documents for
the option a bit. And '-n' won't show the changes of backup

The html(sgml) document says that, 

=== share/doc/html/app-pgresetxlog.html
| The -n (no operation) option instructs pg_resetxlog to print
| the values reconstructed from pg_control and values about to be
| changed, and then exit without modifying anything. This is
| mainly a debugging tool, but can be useful as a sanity check
| before allowing pg_resetxlog to proceed for real.

This seems to have same meaning to the help message. "For
debugging use" also supports your way of understanding the
option, I suppose.
