fix vector-move-right! and vector-move-left!
* libguile/vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
Fix some bugs reported by Michael Lucy -- both variants would happily
write beyond the end, and vector-move-right! didn't increment the
counter before copying in the reverse direction.
* test-suite/tests/vectors.test ("vector-move-left!"):
("vector-move-right!"): Add tests.
