Subject: add_packed_ref(): new function in the refs API.
X-Git-Tag: v1.7.10-rc0~141^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=30249ee68fa5fa63bfb9bb417987b0547253b8e7;p=git.git

add_packed_ref(): new function in the refs API.

Add a new function add_packed_ref() that adds a reference directly to
the in-memory packed reference cache.  This will be useful for
creating local references while cloning.
