The following commands and options now support the standard size
suffixes kB, M, MB, G, GB, and so on for T, P, Y, Z, and Y:
head -c, head -n, od -j, od -N, od -S, split -b, split -C,
tail -c, tail -n.
* doc/coreutils.texi (od invocation, head invocation, tail invocation):
Document support for new size suffixes.
(head invocation, tail invocation):
Document that -n uses the same suffixes as -c.
(tail invocation): More-clearly document what leading "+" does.
* src/head.c (usage, string_to_integer): Support new suffixes.
* src/od.c (usage, main): Likewise.
* src/split.c (usage, main): Likewise.
* src/tail.c (usage, parse_options): Likewise.
