* src/tgba/tgbaexplicit.cc (tgba_explicit::all_accepting_conditions)

Browse source 
Compute all_accepting_conditions_ from neg_accepting_conditions_,
not by browsing the dictionary.  The dictionary also contains
accepting conditions from other automata...  This bug was a
consequence of the change from 2003-07-14.
* src/tgbaalgos/save.cc (save_bfs::start()): Likewise, do not
browse the dictionary to print accepting conditions.  Call
->all_accepting_conditions() instead.
* src/tgba/tgbaproduct.cc (tgba_product::tgba_product): Typo
from 2003-08-22 in the computation of all_accepting_conditions_.
* src/tgbatest/explpro3.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add explpro3.test.
* src/tgbatest/explprod.test, src/tgbatest/explpro2.test,
 src/tgbatest/tripprod.test: Sort the output using Perl.
