[PATCH v3 06/19] apply: split load_preimage() helper function out

From
Junio C Hamano <gitster@pobox.com>
Date

Message-ID
<1339615980-19727-7-git-send-email-gitster@pobox.com>
In-Reply-To
<1339615980-19727-1-git-send-email-gitster@pobox.com>

The function apply_data() gets a patch for a single path, reads the preimage in core, and applies the change represented in the patch.

Separate out the first part that reads the preimage into a separate helper function load_preimage().
