I think it means you get the effect of a "*" right at the start of the
trial completion.

I've now realised, I think, that "trial completion" in the documentation
doesn't mean what I thought it was (i.e. one of the list of
possibilities) --- it means the pattern formed by applying matching
control to what you type which is then matched against one of the list
of possibilities.

So if you type foo then the effect of l:|=* means it will match *foo
against the possibilities, together with the other modifications.

Maybe.
