Instead of showing another column, I changed to show links with isdir=false.
At the cost of two more patches, to allow backpatching docs and maybe separate
commit to make the subtle change obvious in commit history, at least.

I see a few places in the backend and a few more in the fronted using the same
logic that I used for islink(), but I'm not sure if there's a good place to put
that to allow factoring out at least the other backend ones.
