Title:
  Split doesn't check for filetype

Status in coreutils package in Ubuntu:
  New

Bug description:
  Hello! I noticed that Split doesn't check for filetypes before it
  starts splitting the file. As a result, it's possible to eat up CPU
  and Disk memory by passing in a character device as input. I wanted to
  make Split  more robust by adding a patch to check for file type.

  This patch do break some of the tests for Split. The tests that are
  checking Split's ability to "elide empty files" by using /dev/null as
  input fail with this patch, since /dev/null is a character device. I
  would love to modify those tests to use a regular empty file, upon the
  approval of this patch.

  Thanks!
