Pádraig Brady 8482cb9451 csplit: avoid extraenous output files given empty input ...

* src/csplit.c (get_first_line_in_buffer): Don't exit here
upon empty input, rather indicate no input in the return
to let callers handle in a more consistent fashion.
* NEWS: Mention the bug fix.
* tests/csplit/csplit.sh: Add a test case.
