That must be it. It looks like `openssl s_client -quiet' will disable
the interactive interpretation of "R" (and some other commands) at the
start of a line. My man page for `s_client' says:
----
When used interactively (which means neither -quiet nor
-ign_eof have been given), then certain commands are also recognized
which perform special operations. These commands are a letter which
must appear at the start of a line. They are listed below. [...]
R Renegotiate the SSL session (TLSv1.2 and below only).
