Comment by Günter Milde:
Actually, *all* Spanish manuals either fail or have wrong output with
Unicode TeX engines and 8-bit fonts. The reason is known: a bug in Babel
that uses utf8 strings whenever Xe- or LuaTeX is detected.
Always-Babel now set in the example document.
Adapted the autotest categorization:
* fails for some developers (why?)
* wrong output with pdflatex/LuaTeX and DVI (missing landscape slides).
and introduce sublabels
Sublabels section in *.Tests starts with 'Sublabel: name'
and is valid until start of a new sublabel.
'name' contains only ascii characters [a-z]+
