PATCH: larger output file sizes for 'split'

[Evan Hunt]

Here's a one-line patch to split.c (plus a few more lines of doc changes
in that file and coreutils.texi) to allow it to emit output files sized in
gigabytes, terabytes, etc.

(Not that I expect a lot of people to use the terabytes and petabtes and so
forth, but they'll be useful someday, and gigabytes are definitely useful
now.)
