Subject: [PATCH v3 2/5] pretty-print: simplify the interaction between pp_handle_indent() and its caller
Date: Wed, 23 Mar 2016 16:23:43 -0700 [thread overview]
Message-ID: <1458775426-2215-3-git-send-email-gitster@pobox.com> (raw)
In-Reply-To: <1458775426-2215-1-git-send-email-gitster@pobox.com>
Instead of sometimes handling the output itself and some other times
forcing the caller handle the output, make the helper function
pp_handle_indent() responsible for the output for all cases.
