ACK for being mechanical.  However...

My review of patch 30/31 made me revisit this patch.  It has an empty
while loop.  Should we enforce a particular style where all empty-bodied
loops should use a more obvious style to prove that we knew what we were
doing?  For example:

while ((rc = libssh2_session_startup(session, sock)) ==
       LIBSSH2_ERROR_EAGAIN)
    ; /* empty */

or

while ((rc = libssh2_session_startup(session, sock)) ==
       LIBSSH2_ERROR_EAGAIN) {
    /* empty */
}

If so, how would we enforce such a style?
