Btw, there are other places where \small runs smoothly. It is *just*
on this table that it has issues.

Interesting... yeah, that could be possible.

Nah... Without tabularcolumns, LaTeX usually got sizes wrong and don't
always place things at the right positions I'm actually considering 
adding it to all media tables, in order to be less dependent on
LaTex automatic cells resizing - with doesn't seem to work too well.

So, better to keep it, even if it works without
\small. Btw, tried your patch here (without tabularcolumns) on
Sphinx 1.6 (tomorrow, I'll do tests with other version). There, the
last "(bits x-y)" ends by being wrapped to the next line.

Yet, I guess the enclosed diff (or something like that) would be
good enough (applied after my own patch, just to quickly test it). 

I'll play more with it tomorrow.

Thanks,
Mauro
