Since 2023-03-22, Gnulib implements the %b directive in the *printf-posix
modules. This patch updates some unit tests to also test the %b directive.
2024-06-30 Bruno Haible <br...@clisp.org>
*printf-posix-tests: Strengthen tests.
* tests/test-fprintf-posix.h (test_function): Test %b directive.
* tests/test-printf-posix.h (test_function): Likewise.
* tests/test-dprintf-posix.c (test_function): Likewise.
* tests/test-printf-posix.output: Update expected test result.
