Subject: Make split condition depend on ~0, not 0.
X-Git-Url: https://git.michaelhowe.org/gitweb/?a=commitdiff_plain;h=55944d161c80af45ad60e8fe46a02e09501ccee2;p=packages%2Fb%2Fbup.git

Make split condition depend on ~0, not 0.

Otherwise we could end up splitting on one-byte blocks, which is pretty
dumb.
