Subject: enable separate reflog for HEAD
X-Git-Tag: v1.5.0-rc4~49^2~10
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=bd104db164d7f2a714aa0f1cdf89fd89fee6c00a;p=git.git

enable separate reflog for HEAD

If HEAD is tied to a branch then both logs/HEAD and logs/heads/<branch> are
updated.  This is also true for any symbolic refs in general, but only HEAD
will see its reflog created automatically.
