bug#20810: 25.0.50; tabulated-list is broken

[Artur Malabarba <bruce.connor.am@gmail.com>]

Ok I've spotted the problem. The logic I implemented assumed that the
`tabulated-list-printer' function (which is used to print each entry)
would always leave point after the printed content, which is not what
debbugs does. Debbugs uses this to also print some content at the top
and bottom of the buffer the first time it is called

I'll find a better way to write this.
