It's used further down, but it's overwritten before, so it's

branchmap: add seek() to end of file before calling tell() on append open()
This is similar to
48c232873a54, which was subsequently modified in
19f5dec2d61f
for 2.4. Unexpected test changes on Windows occurred without this.
tests: fix test-casefolding.t output for branchcache
This belongs with
7d63398fbfd1. I assume that the failure to read is OK,
because there is similar output in test-convert-svn-encoding.t.
