Subject: sequencer: report when noop has an argument
X-Git-Tag: v2.16.0-rc1~1^2~1
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/66afa24fb36f15c49aed76be2f04bd23dd0e55c8

sequencer: report when noop has an argument

The noop command cannot accept any argument, but we never told the user
about any bogus argument. Fix that.

while at it, mention clearly when an argument is required but missing
(for commands *other* than noop).
