Before my appctl patch the man page looked like this:
ovs-appctl [--target=``<target> | ``-t <target>] [--time‐
out=``<secs> | ``-T <secs>] [--format=``<format> | ``-f <for‐
mat>] [--pretty] <command> [<arg>…]
See all the "``" quotes in the rendered page. After the change, they
are gone:
ovs-appctl [--target=target | -t target] [--timeout=secs | -T
secs] [--format=format | -f format] [--pretty] command [arg
...]

Yes, because `` requires a space afterwards. A non-rendered escaped
space ('\ ') works as well.

It is consistent with how man pages are normally written.

We should change other pages as well, so they look like typical man pages,
but it is outside of scope for this patch set.
