Hmm.  When did this spelling change?  In old man pages
(http://reviewed.homelinux.org/man/df/), I see BLOCKSIZE.
I assume that the $BLOCKSIZE (no _) spelling is a BSDism... But I do note
that the POSIX spec lists it as a proposed extension, with that spelling.

It seems to me like it would be reasonable to use $BLOCKSIZE if $BLOCK_SIZE
isn't set, simply because it's widely used elsewhere.  (Convenient for me that
I ran into this while writing an article about shell script portability.)
