    * src/ltlast/multop.cc, src/ltlast/multop.hh: Declare AndNML
    operator.
    * src/ltlparse/ltlscan.ll: Distinguish "&" and "&&".
    * src/ltlparse/ltlparse.yy: Handle them both as "And" for LTL
    formula, use AndNML or And for rational expressions.
    * src/ltlvisit/tostring.cc: Adjust to distinguish "&" and "&&" in
    rational expressions. Also use {braces} to group rational
    expressions.
    * src/tgbaalgos/ltl2tgba_fm.cc
    (ratexp_trad_visitor::ratexp_trad_visitor): Remove the possibility
    to select the empty_word should act like true, and fix the rules
    for Closure and NegClosure to rely on constant_term instead.
    (ratexp_trad_visitor::visit) Adjust the And translation to also
    support AndNML.
    (ratexp_trad_visitor::recurse_and_concat): Introduce this new
    method to simplify some calls to recurse(f, to_concat_).
    * src/tgbatest/ltl2tgba.test: Add more test cases.
    * src/ltlvisit/basicreduce.cc, src/ltlvisit/consterm.cc,
    src/ltlvisit/contain.cc, src/ltlvisit/mark.cc,
    src/ltlvisit/nenoform.cc, src/ltlvisit/syntimpl.cc,
    src/tgba/formula2bdd.cc, src/tgbaalgos/eltl2tgba_lacim.cc,
    src/tgbaalgos/ltl2taa.cc, src/tgbaalgos/ltl2tgba_lacim.cc: Add
    missing cases in switches.
