From: Daniel Llorens <daniel.llor...@bluewin.ch>
* libguile/array-handle.c (scm_array_handle_writable_elements): Fix
error message.
* libguile/array-map.c (scm_array_slice_for_each): Support non-zero
lower bounds. Fix error messages.
* test-suite/tests/array-map.test: Test scm_array_slice_for_each with
non-zero lower bound argument.
