c_locale.h (__convert_from_v): Don't use a default for __prec, assume __prec >= 0 and simplify.

	* config/locale/generic/c_locale.h (__convert_from_v): Don't
	use a default for __prec, assume __prec >= 0 and simplify.
	* config/locale/gnu/c_locale.h (__convert_from_v): Likewise.
	* include/bits/locale_facets.tcc (money_put<>::do_put(long double)):
	Pass format "%.*Lf" + precision == 0, equivalent to "%.0Lf".
