Hi Hans,

The removal of typo-spa.lua breaks the format generation in mkiv:

loading         > ConTeXt Typesetting Macros / Wrapping
resolvers       > lua > loading file '/usr/share/texmf/tex/context/base/mkiv/typo-wrp.lua' succeeded
close source    > level 1, order 226, name '/usr/share/texmf/tex/context/base/mkiv/typo-wrp.mkiv'
open source     > level 1, order 227, name '/usr/share/texmf/tex/context/base/mkiv/typo-spa.mkiv'
loading         > ConTeXt Typesetting Macros / Spacing
resolvers       > lua > unknown file 'typo-spa.lua'

Adding the file back creates the formats again.
