csplit: avoid buffer overrun when writing more than 999 files

Browse Source 
Without this fix, seq 1000 | csplit - /./ '{*}' would write
the NUL-terminated file name, xx1000, into a buffer of size 6.
* src/csplit.c (main): Use properly sized file name buffer.
* NEWS (Bug fixes): Mention it.
* tests/misc/csplit-1000: New test to trigger the bug.
* tests/Makefile.am (TESTS): Add misc/csplit-1000.
