Can you find a complete list of BSD programs that use getbsize,
and which contexts they use it in?

Here's why I'd like to know the details.  OpenBSD 3.2 'ls' treats
BLOCKSIZE differently than coreutils-5.2.0 'ls' treats BLOCK_SIZE.
The latter affects the st_size column, but the former doesn't.  (See
below.)  So, even if we make BLOCK_SIZE default to BLOCKSIZE, the
emulation won't be quite right for "ls".  I'm worried that there are
other problems in other programs.
