Fixes#366, reported by Simon Jantsch.
* spot/twaalgos/translate.cc: type_&Generic will also match if
type_==BA... use type_==Generic instead.
* tests/core/unambig.test: Add a test corresponding to Simon's report.
* NEWS: Describe the bug.
Reported by Simon Jantsch and David Müller.
* spot/twaalgos/isunamb.cc (is_unambiguous): Rewrite wihtout assuming
that the product of two accepting SCCs is accepting, Also use
the result of is_accepting_scc()/is_rejectng_scc() when available.
* spot/twaalgos/sccinfo.cc, spot/twaalgos/sccinfo.hh: Make it
possible to check the acceptance of a unique SCC.
* tests/core/unambig.test: Add more test cases.
Reported by Simon Jantsch and David Müller.
* tests/core/unambig.test: Test the issue.
* spot/twaalgos/isunamb.cc: Fix it.
* NEWS: Mention it.
* THANKS: Add Simon.
Our use of
ltl2tgba=ltl2tgba
autfilt=autfilt
...
all over the test cases comes from the time where those tools were not
in PATH and we actually had something like
ltl2tgba=../../bin/ltl2tgba
autfilt=../../bin/autfilt
But today that is useless, and we prefer to write ltl2tgba rather than
$ltl2tgba, so let's remove this old cruft.

Avoid calling scc_info::determine_unknown_acceptance on the product, as
suggested in #188.
* spot/twaalgos/isunamb.cc (is_unambiguous): Rewrite.
* tests/core/unambig.test: Add the automaton from #188.
* NEWS: Mention the improved function.
* spot/twaalgos/mask.cc,

Suggested by František Blahoudek.

* tests/core/complementation.test: Adjust test case.
* tests/core/ltlcross3.test, tests/core/unambig.test: More tests.
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.

Fixes#81.
This required a small change to the bounded-star-normal-form to prevent
infinite recursion.
* spot/tl/simplify.cc: Implement these rules.
* doc/tl/tl.tex, NEWS: Document them.
* tests/core/reduccmp.test: Add tests, and adjust others.
* tests/core/unambig.test: Replace formula that used to generated an
ambiguous automaton, but now generates a deterministic one.
Report from Joachim Klein.
* spot/twaalgos/ltl2tgba_fm.cc: Set the property, do not read it.
* tests/core/unambig.test: Add a test.
* NEWS: Mention the bug.
