This patch makes further coding style fixes where code was breaking lines after an operator, contrary to the GNU Coding Standards. As with the previous patch, it is limited to files following a reasonable approximation to GNU style already, and is not exhaustive; more such issues remain to be fixed. Tested for x86_64, and with build-many-glibcs.py. * dirent/dirent.h [!_DIRENT_HAVE_D_NAMLEN && _DIRENT_HAVE_D_RECLEN] (_D_ALLOC_NAMLEN): Break lines before rather than after operators. * elf/cache.c (print_cache): Likewise. * gshadow/fgetsgent_r.c (__fgetsgent_r): Likewise. * htl/pt-getattr.c (__pthread_getattr_np): Likewise. * hurd/hurdinit.c (_hurd_setproc): Likewise. * hurd/hurdkill.c (_hurd_sig_post): Likewise. * hurd/hurdlookup.c (__file_name_lookup_under): Likewise. * hurd/hurdsig.c (_hurd_internal_post_signal): Likewise.
