Stop reading Liquid Tracker instrument names out-of-bounds. (libxmp#814)
Browse files Browse the repository at this point in the history 
libxmp was copying 31 bytes from the 30 byte instrument name, so it
would include the first byte of the instrument software string.
Most of the time the software string is blank, so this wasn't
noticed.
