c5476200 - format-c: Recognize size specifiers w8, w16, w32, w64, wf8, wf16, wf32, wf64.

format-c: Recognize size specifiers w8, w16, w32, w64, wf8, wf16, wf32, wf64. * gettext-tools/src/format-c.c (INVALID_SIZE_SPECIFIER): New macro. * gettext-tools/src/format-c-parse.h (format_parse_entrails): Accept only one size specifier, not a sequence of size specifiers. Accept "wN" and "wfN", where N = 8, 16, 32, 64. Reject integer size specifiers for floating-point directives. Reject integer size specifiers other than "l" for %c and %s. * gettext-tools/tests/format-c-1: Add more test cases. * gettext-tools/tests/format-c-2: Likewise. * NEWS: Mention it.
