dd: fix conv=ascii, conv=ebcdic, conv=ibm to match POSIX
Problem reported by Don Baggett in <http:/bugs.gnu.org/17422>. * NEWS: * doc/coreutils.texi (dd invocation): Document this. * src/dd.c (conversions): conv=ascii implies conv=unblock. conv=ebcdic and conv=ibm imply conv=block. (ascii_to_ebcdic, ebcdic_to_ascii): Correct to match POSIX 1003.1-2013. * tests/dd/ascii.sh: New file. * tests/local.mk (all_tests): Add it.
