I committed this. It should fix it. Please test it, since I don't have access
to a HP-UX 10 machine. To test it, create a test directory through the command
$ ./gnulib-tool --create-testdir --with-tests --dir=/tmp/testdir \
fprintf-posix printf-posix snprintf-posix sprintf-posix vasnprintf-posix \
vasprintf-posix vfprintf-posix vprintf-posix vsnprintf-posix vsprintf-posix

Fix *printf behaviour regarding the left-adjust flag on HP-UX 10.20.
* m4/printf.m4 (gl_PRINTF_FLAG_LEFTADJUST): New macro.
* lib/vasnprintf.c (VASNPRINTF): Handle NEED_PRINTF_FLAG_LEFTADJUST.
* m4/vasnprintf.m4 (gl_PREREQ_VASNPRINTF_FLAG_LEFTADJUST): New macro.
(gl_PREREQ_VASNPRINTF_WITH_EXTRAS): Invoke it.
* m4/fprintf-posix.m4 (gl_FUNC_FPRINTF_POSIX): Invoke
gl_PRINTF_FLAG_LEFTADJUST and test its result. Invoke
gl_PREREQ_VASNPRINTF_FLAG_LEFTADJUST.
* m4/snprintf-posix.m4 (gl_FUNC_SNPRINTF_POSIX): Likewise.

left-adjust flag.
* tests/test-snprintf-posix.h (test_function): Likewise.
* tests/test-sprintf-posix.h (test_function): Likewise.
