Subject: [PATCH 16/23] should_pack_ref(): new function, extracted from `files_pack_refs()`
Date: Wed, 17 May 2017 14:05:39 +0200 [thread overview]
Message-ID: <2e104ca5ff7112bc00e0a482b02a496585eee77d.1495014840.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1495014840.git.mhagger@alum.mit.edu>
Extract a function for deciding whether a reference should be packed.
It is a self-contained bit of logic, so splitting it out improves
readability.
