* libguile/filesys.c, libguile/random.c, libguile/stime.c, libguile/trees.c, libguile/validate.h: use scm_is_vector instead of scm_is_simple_vector. * libguile/sort.c (scm_sort_x, scm_sort, scm_stable_sort_x) (scm_stable_sort): Remove scm_is_vector check; scm_is_array is sufficient. * test-suite/tests/arrays.test: Fix header. * test-suite/tests/random.test: New coverage test covering random:normal-vector!. * test-suite/Makefile.am: Include random.test in make check.
