Comment 2 for bug 1609368

There seems to be an issue with it not being displayed as required in the help output. For now at least it _is_ required.

There is another issue about the error message being unclear.

"snap find" without arguments has not shown "all available snaps" in quite a while; it would show 100 arbitrary snaps. That is expensive and never what the user wanted, so in 2.11 we stopped doing that.
