If no input have been specified, and the standard input is not a tty all tools now default to reading it. If standard input is a tty, all tools display an error message. Additionally, - is now a shorthand for -F- in all tools. * NEWS: Summarize this. * bin/common_finput.cc, bin/common_finput.hh (check_no_formulas, check_no_automaton): New functions that implement the above istty() logic. * bin/autfilt.cc, bin/dstar2tgba.cc, bin/ltl2tgba.cc, bin/ltl2tgta.cc, bin/ltlcross.cc, bin/ltldo.cc, bin/ltlgrind.cc: Use these function, and recognize '-' if it was not the case. * tests/core/acc_word.test, tests/core/ltldo.test, tests/core/minusx.test, tests/core/readsave.test, tests/core/unambig.test: Adjust some tests to exercise this. * doc/org/autfilt.org, doc/org/csv.org, doc/org/dstar2tgba.org, doc/org/ltl2tgba.org, doc/org/ltlcross.org, doc/org/ltlfilt.org, doc/org/oaut.org: Adjust the documentation and simplify some examples.
