Shouldn't this be
git tag -l [[--[no-]contains|--points-at|--[no-]merged] <commit>]
[<pattern>]
i.e. if you are giving <commit> you need how that commit is used in
filtering, but you do not have to give any such filter when listing,
and <pattern>, when given, is used to further limit the output, but
it also is optional.

Who are "we"?
When any option that only makes sense in the list mode
(e.g. `--contains`) is given, the command defaults to
the `--list` mode.
By the way, do we catch it as a command line error when options like
`--points-at` are given when we are creating a new tag?

Don't we want to make sure we do the defaulting only upon !cmdmode?
Doesn't this start ignoring
tag -a -m foo --points-at HEAD bar
as an error otherwise?

And I do not think removal of these check is a good idea at all.
Perhaps you were too focused on '-l' that you forgot that people may
be giving an explicit option like -a or -s, in which case these
error checks are still very sensible things to have, no?
