Hi,

I updated context-minimals today and \mainlanguage[es] is broken.

Example:

  \mainlanguage[es]
  \starttext
  \chapter[]{Cap1}
  Hello World.
  \stoptext

$ texexec --pdf example.tex

! Undefined control sequence.
<argument> \itulo

The problem is lang-ita.tex :

--- lang-ita.tex    2009-08-26 18:15:38.200286872 +0200
