Add support for splitting at gigabyte boundaries. [1]
Also make both lowercase and uppercase suffix letters work as byte-count suffixes, i.e. the following two commands are equivalent now: % split -b 4m foo % split -b 4M foo Submitted by: Roman Divacky [1] Lots of help by: cperciva Reviewed by: cperciva MFC after: 1 week
