If one of the blocks which are subordinate to a @(trailer)
happen to request a successful termination by invoking @(accept)
the position must not advance into the trailer material.
* match.c (v_trailer): Added an unwind protect which
detects that an accept is taking place and adjusts the return value to
restrict the input position at the point given to trailer.
(accept_fail): Use uw_block_return_proto instead of uw_block_return
and pass the symbol as the protocol identifier.
* unwind.c (uw_current_exit_point): New function.
(uw_block_return): Function renamed to uw_block_return_proto;
takes new parameter which is stored in the block structure.
* unwind.h (struct uw_block): New member, protocol.
(uw_block_return): Becomes an inline wrapper for uw_block_return_proto.
(uw_block_return_proto, uw_current_exit_point): Declared.
* txr.1: Interaction between @(trailer) and @(accept) documented.
