we removed a useless assertion that was forcing matita to edit just matita files
matita's editor is good on its own and has interesting facilities including predefined virtuals
in lambdadelta we use matita to edit the .tbl files containing notation from the .ma's
and we use matita as well to edit predefined_virtuals.ml
we still wonder how we could do this up to now despite the assertion!
