The builtin returns true with garbage arguments

[faho]

builtin -- whatever

will always just return true without doing anything because it hasn't been told to query (-q) or to list the names (-n) and so just does nothing.

This is not a regression in the rust version, this is how it worked in 3.6.1 as well.

Of course builtin whatever is the decorator version, and will try to run a builtin called "whatever", but as soon as you add the -- it'll call the builtin.

The command and time builtins open their help if called like that - which also isn't great, tbh, because it opens a pager and I find it unexpected. I'd expect just a regular error.

In the interest of consistency, I'll make it open the help first.

(@zanchey This could be backported to 3.7.0, I'll fix it in the rust version first because it's not a big deal)

@faho let me know if you still want to fix this for 3.7.0

It's fine to skip it - it's a weird reaction to already buggy code in a small edge case, and nobody stumbled over it in practice (I found it by snooping around for builtin -- $foo).
