[PATCH 4/3] git-http-backend: avoid multi-arg print statemtents

[Eric Wong <e@80x24.org>]

Even with output buffering disabled via IO::Handle::autoflush,
writes are not atomic unless it is a single argument passed to
"print".  Multiple arguments to "print" will show up as multiple
calls to write(2) instead of a single, atomic writev(2).
