Subject: [PATCH] contrib/mbox-split: abort after usage if wrong number of args

Previously, attempting to run the script without args will print:

$ ./mbox-split
Usage: ./mbox-split <input.mbox> <max size with SI suffix>
Traceback (most recent call last):
  File "/tmp/./mbox-split", line 25, in <module>
    if sys.argv[2].endswith(suffix):
IndexError: list index out of range
