Subject: cmd/newliner: if input starts getting too long, print it out.
X-Git-Url: https://git.michaelhowe.org/gitweb/?a=commitdiff_plain;h=26a32bacfa97dcb2297f3c0723ef7507bcaf056a;p=packages%2Fb%2Fbup.git

cmd/newliner: if input starts getting too long, print it out.

This prevents output that doesn't have any newlines from being buffered
forever (eg. the output of 'bup split -vv').
