This (I think last) patch for truncated-print adds support for
bitvectors and also makes sure to print the correct array print prefix
when it's not trivial (non-zero base indices or zero dimensions). For
this I need to pull out a piece of scm_i_print_array as
array-print-prefix.

* libguile/arrays.c (scm_i_print_array_prefix, scm_array_print_prefix):
New functions.
(scm_i_print_array): Reuse scm_i_print_array_prefix(). Make sure to
release the array handle.
* module/ice-9/pretty-print.scm (truncated-print): Add a case for
bitvectors. In the array case, use (array-print-prefix) to compute the
prefix.
* test-suite/tests/print.test: Add tests with bitvectors and custom base
indices in arrays.
