    strings: Print strings that have the minimum length
    
    Previously, there was an off-by-one error when determining whether
    to print a strings, so when the string was exactly the minimum
    length, it was not printed.
    
    This fixes a bug with an x264 configure test, which expects to find
    a string of length 4 (BIGE/EBIG) to detect system endianness.
