LSR: caps font-shape snippet doesn't work

[Valentin Villenave]

Hi everybody,

Can anyone make this snippet work?

http://lsr.dsi.unimi.it/LSR/Item?id=100

I added it last year (it was in a set of regtests Graham sent me, I
think), but IIRC it never worked. I thought it was a version
compatibility problem, but it appears not to be. I think it might be
because the fonts we're using don't have a "caps" variant, but I may
be wrong.

Cheers,
Valentin
