I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

As reported in bug 23280, scanf functions produce incorrectly rounded
result for floating-point formats in FE_UPWARD and FE_DOWNWARD modes,
because they pass the input with sign removed to strtod functions, and
then negate the result if there was a '-' at the start of the input.
This patch fixes this by arranging for the sign to be passed to strtod
rather than scanf doing the negation itself. In turn, keeping the
sign around in the buffer being built up for strtod requires updating
places that examine char_buffer_size (&charbuf) to allow for the sign
being there as an extra character.
Tested for x86_64.
[BZ #23280]
* stdio-common/vfscanf.c (_IO_vfscanf_internal): Pass sign of
floating-point number to strtod functions rather than possibly
negating result of those functions.
* stdio-common/tst-scanf-round.c: New file.
* stdio-common/Makefile (tests): Add tst-scanf-round.
($(objpfx)tst-scanf-round): Depend on $(libm).
