* test-suite/tests/format.test:
* test-suite/tests/regexp.test:
* test-suite/tests/srfi-19.test:
* test-suite/tests/tree-il.test: Make sure 'setlocale' is defined before
calling it.
* doc/ref/misc-modules.texi (Formatted Output): Document ~h. Recommend
use of ~h instead of ~:d.
* module/ice-9/format.scm (format): Add support for ~h.

destination port.
* module/ice-9/format.scm (format:parse-float): Accept a number, and
