Subject: Fix the names in the reflog for checkouts
X-Git-Tag: v1.1.0.201109071825-rc3~2
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=refs%2Fchanges%2F39%2F4139%2F2;p=jgit.git

Fix the names in the reflog for checkouts

We were diverging from the reference implementation. Always use the
ref we checkout to as the to-branch the reflog and avoid the
refs/heads both in the from-name and to-name.
