windmove not working well

[Joe Corneli]

windmove.el (/path/to/emacs/lisp/windmove.el) did not work for me
out of the box.  When I loaded it and tried windmove-down above I
got an error message--

windmove-do-window-select: No window down from selected window

even though there was a window down from the selected window.

Stefan Daschek suggested increasing the value of
windmove-window-distance-delta.

Setting it to 2 made the movement functions work sometimes; with
higher values for this variable, they didn't seem to work at all.
What I saw with it set to 2 and with my windows set up like this,

        .....................
        .                   .
        .    c    C         .
        .....................
        .    a    .         .
        .    A    .    B    .
        .         .         .
        .....................
        .    d    D         .
        .....................

was as follows:

windmode-right from `A' gets me to window `B' (good)
windmove-right from `a' puts me in window `C' (bad)
windmove-down from `c' puts me in window `A' (good)
windmove-up from `d' triggers the error message (bad)
