So it seems this problem has been around for a while, and looks like it
is due to a change in texi2dvi in texinfo 5.0 or late 4.x, see [1].

I guess it's not very noticeable since it only occurs when doing 'make
dvi', which doesn't happen by default.

Attached is a different and perhaps cleaner workaround to the one in
that thread.

Subject: [PATCH] Use '@sp 1' rather than '@*' to workaround a change in
 texi2dvi.

Since about TexInfo 5.0, using '@*' immediately after a table causes a 'You
can't use `@unskip' in vertical mode' error.
