[pushed] Fix --help output

[Tom Tromey <tom@tromey.com>]

In commit 9e69a2e127940cc5, which introduced "command" styling, I
accidentally made gdb's --help output mention the "stream" command,
rather than the "help" command.

While doing this I also found a spot where --help output was
incorrectly formatted.  This patch fixes this as well.

I'm going to backport this to the gdb-17 branch as well.
