Frankly, I wouldn't know what to write. That the number should be ignored? We'd 
better remove it in the first place.
Of course, someone is bound to complain if such a thing were attempted.

Thank you -- specifically, it doesn't work for BSD ls.
We could set BLOCKSIZE to 1024 -- this works on both GNU and BSD ls -- and then 
post-process the output. Or insert the switch `-k', which is in Posix (in 
contrast to BLOCKSIZE or BLOCK_SIZE), but I don't know if that would break any 
customisation.

It's all very fragile. Migrating to a fully built-in directory lister seems to 
be the only sane way out, and it's considerably more work than I anticipated 
for this little detail.
