* src/tgbaalgos/gtec/gtec.cc, src/tgbaalgos/gtec/gtec.hh:

(couvreur99_check_shy_ssp): Add a onepass_ attribute to
disable the "shyness", and do not increment pos before calling
find_state since gspn's implementation uses it.
* iface/gspn/ssp.cc: Enable "onepass_" for all "shy" variants,
and also fix find_state for the case where onepass_ is
disabled (but I do not yet know why the latter fix isn't enough).
