True, but it's possible on most of them (obtw, the output in question
is on stderr, not stdout):
Unix: openssl genrsa 2> /dev/null
VMS: define/user sys$error nla0:
openssl genrsa

I still say that's the only way to do it. Trying to fiddle with
BIO_printf() and have it "magically" see if it's supposed to be quiet
or not is asking for lots of trouble. Also, it's not that many
commands that have that kind of "intrusive" printout.

Well, you can always see what is there already in the doc/ directory
tree and fill the gaps (there are gaps, absolutely, not question about
it :-)).
