    Fix out of boundary read.
    
    If a binary file which starts with 0x00 is edited, xrdb performs
    an off-by-one read outside of its buffer.
    
    The fix is simple: Do not try to append an empty string to buffer,
    which would be a no-op anyway.
    
    Proof of Concept (compile with -fsanitize=address):
    
    $ dd if=/dev/zero bs=1 count=1 of=poc.txt
    $ xrdb -edit poc.txt
