I believe that this problem comes from oggenc sending the help message
to stderr instead of stdout. Under unix, both "oggenc -h > ogghelp.txt"
and piping the output to less or more don't work (for me). The only way
to read the output on dumb terminals with no scrollback buffer is to do
"oggenc -h 2> ogghelp.txt". No idea whether this works under
Windows/DOS, but I guess not.

Michael, does sending the help to stderr have any purpose I don't see
here? If not, I think it would be a nice idea to change that to stderr
...

P.S.: Oops, Michael answered already. Anyways, see this as a hint how to
dump the help to a file. :P
