[patch] Add numerical suffixes to split

[Jesse Kornblum]

Hi there! I'm a computer crime investigator for the United States Air
Force and have developed a patch to improve the functionality of
'split.' We use split to break large files generated by dd into smaller
chunks. Unfortunately, our analysis programs want these chunks to have
numerical suffixes (e.g. .001, .002, .003, etc) instead of the
alphabetical ones that split currently generates. The patch below
against split.c in Coreutils 5.0 adds numerical suffixes to split. Could
it be included in the next release of CoreUtils?

Thanks!
