I had a look at what tabulated-list-mode does, and it's a lot of code.
(And it doesn't really work well -- toggling the line numbers on and
then off again doesn't restore the column names).

I'm surprised that that's necessary -- surely
`display-line-numbers-mode' should itself fix up the header line?  That
is, there should be a header line format construct that modes can add to
the front of `header-line-format' that's controlled by
`display-line-numbers-mode'.

Eli, does this sound like a plan to you?
