https://lists.gnu.org/archive/html/bug-gnulib/2016-02/msg00013.html

* lib/argp-fmtstream.c (__argp_fmtstream_update): Flush output as soon
as possible.
* lib/argp-fmtstream.h (struct argp_fmtstream): Member point_offs is
no longer needed.
* lib/argp-help.c (indent_to): Flush output to avoid a spurious
newline before an overlong word.
