beam.cc: avoid calculating an invalid reference
In calc_beam_segments, an invalid reference to a neighboring segment
was calculated (and not used) at the extreme ends of the beam. This
caused segfaults on Fedora. Since the reference is used at most twice
anyway and in the same _expression_, it seems easier to just use the
_expression_ directly (the invalid cases are then skipped due to
short-circuit evaluation).
