Joseph Myers c5f65462a2 Break lines before not after operators, batch 4.
This patch fixes further coding style issues where code should have
broken lines before operators in accordance with the GNU Coding
Standards but instead was breaking lines after them.

Tested for x86_64, and with build-many-glibcs.py.

	* stdio-common/vfscanf-internal.c (ARG): Break lines before rather
	than after operators.
	* sysdeps/mach/hurd/setitimer.c (timer_thread): Likewise.
	(setitimer_locked): Likewise.
	* sysdeps/mach/hurd/sigaction.c (__sigaction): Likewise.
	* sysdeps/mach/hurd/sigaltstack.c (__sigaltstack): Likewise.
	* sysdeps/mach/pagecopy.h (PAGE_COPY_FWD): Likewise.
	* sysdeps/mach/thread_state.h (machine_get_basic_state): Likewise.
	* sysdeps/powerpc/powerpc64/tst-ucontext-ppc64-vscr.c
	(PPC_CPU_SUPPORTED): Likewise.
	* sysdeps/unix/sysv/linux/alpha/a.out.h (N_TXTOFF): Likewise.
	* sysdeps/unix/sysv/linux/generic/wordsize-32/overflow.h
	(stat_overflow): Likewise.
	(statfs_overflow): Likewise.
	* sysdeps/unix/sysv/linux/tst-personality.c (do_test): Likewise.
	* sysdeps/unix/sysv/linux/tst-ttyname.c (eq_ttyname): Likewise.
