Nothing is lost in these since the functions already required true typed vectors, the extra arguments didn't serve any purpose. Changing my mind from (vec) to (vec, lenp), though. Will fix vector/bitvector next. * libguile/srfi-4.h: scm_TYPEvector_(writable_)elements take (vec, lenp). * libguile/srfi-4.c: Fix implementation. * libguile/bitvectors.c: Fix use. * test-suite/standalone/test-srfi-4.c: Fix old test and write variant with full array handle interface. * doc/ref/srfi-modules.texi: Fix doc for srfi-4 scm_TYPEvector_(writable_)elements.
