update regress tests
sort entries, fix typo
Update to the latest development version.

All features of the "old" grammar are supported now.  The regress
tests are updated to use the new grammar but we keep the same names to
have a 1:1 comparison with the old gramar.  All of them should succeed
now.  Thanks to Andre de Oliveira for his help.
