Ensure key descriptions in status bar are always null-terminated.
Key descriptions are just strncpy()'ed to key[], with KEYS_KEYLEN as maximum character count. This leads to a non-null-terminated string if the source pointer actually points to a string with a length of KEYS_KEYLEN bytes. Always appending a null character fixes this.
