Subject: Simplify parsing branch switching events in reflog
X-Git-Tag: v1.6.2-rc0~70^2~1

Simplify parsing branch switching events in reflog

We only accept "checkout: moving from A to B" newer style reflog entries,
in order to pick up A.  There is no point computing where B begins at
after running strstr to locate " to ", nor adding 4 and then subtracting 4
from the same pointer.
