Re: [PATCH 1/2 jk/war-on-sprintf] read_branches_file: plug a FILE* leak

> The earlier rewrite f28e3ab2 (read_branches_file: simplify string handling)
> of read_branches_file() lost an fclose() call. Put it back.
>
> As on Windows files that are open cannot be removed, the leak manifests in
> a failure of 'git remote rename origin origin' when the remote's URL is
> specified in .git/branches/origin, because by the time that the command
> attempts to remove this file, it is still open.
