ltlgrind: improve error message when formulas are missing
The error message, inherited from ltl2tgba, used to say "No formula to translate", but "translate" isn't appropriate here. * bin/common_finput.cc, bin/common_finput.hh (check_no_formula): Allow "translate" to be changed. * bin/ltlgrind.cc: Change it. * tests/core/ltlgrind.test: Test it.
