Sync from coreutils. * modules/yesno (Depends-on): Add getline. * gethrxtime.c, gethrxtime.h, getpass.h, mountlist.h, path-concat.c, regex.h, strtoll.c, unlocked-io.h, xtime.h: White space changes only. * makepath.c (make_path): Port to hosts where leading "//" is special. * yesno.c: Include getline.h, not ctype.h. (yesno): Don't remove leading white space; POSIX doesn't allow it. Use getline to remove arbitrary restriction on response length.
