usr.bin/du : du.1 du.c
Log message:
Add the -d flag (limit display depth) for compatibility with FreeBSD,
DragonFly, NetBSD and GNU coreutils, even though it's not POSIX.
Actually, this simplifies the code rather than complicating it.
Because -a and -d need not be mutually exclusive (as observed by
millert@) and -s is identical to -d 0, -a and -s are no longer
mutually exclusive, but -as and -sa are now the same as -s.
That is explicitly allowed by POSIX.
Based on a patch from William Orr <will at worrbase dot com>,
but extensively massaged and HISTORY added by me.
feedback and ok millert@
