Subject: read-cache.c: move code to copy ondisk to incore cache to a helper function
X-Git-Tag: v1.7.11-rc0~76^2~6
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3fc22b53313ff035da145b2cb59e587ff3868654;p=git.git

read-cache.c: move code to copy ondisk to incore cache to a helper function

This makes the change in a later patch look less scary.
