    Fix a valgrind warning in the Keen DIFF_HARD solver code.
    
    The solver's array ctx->iscratch[] is used for a completely different
    purpose in the DIFF_HARD code, compared to what it's used for in
    DIFF_EASY and DIFF_NORMAL. In particular, a different number of
    elements of the array are used - but the code which sets up the array
    was not correctly initialising all of them.
    
    I was also unable to find any clear comment that even explained _that_
    the purpose of the array was entirely different between the two cases,
    let alone explaining _what_ the two purposes were. So I've written
    some comments as part of this commit, which should make things a bit
    less confusing next time. (Though not much, I admit.)
