Bug#905390: musepack-tools: wavcmp never shows usage

[Benjamin Barenblat]

Package: musepack-tools
Version: 2:0.1~r495-1+b1
Severity: normal
Tags: upstream

wavcmp only displays usage if `4 < argc && argc < 3`
(https://sources.debian.org/src/libmpc/2:0.1~r495-1/wavcmp/wavcmp.c/#L49),
which is always false. That should probably read
`4 < argc || argc < 3`.
