Subject: rename_ref(): handle the case when the reflog of a ref does not exist
X-Git-Tag: v1.6.0.4~5^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=450d4c0f5a966b3f5835107ec4d8c344c8c25908;p=git.git

rename_ref(): handle the case when the reflog of a ref does not exist

We tried to check if a reflog of a ref is a symlink without first
checking if it exists, which is a bug.
