update in test files for @caption, test @verb

[Patrice Dumas]

Hi,

I updated the files testing for weird things in @caption by adding a
@shortcaption, such that there is no confusion with normal errors coming from
@listoffloat.

@xref in @caption works, thus I don't attach it. However @ref in @shortcaption
doesn't work, thus I attach a file with this test, but disregard it if you
think @ref shouldn't work in @shortcaption.

I also tested @verb in @caption and @shortcaption and both failed. I attached
the test files.
