log: prepare log/log-tree to reuse the diffopt.close_file attribute
We are about to teach the log-tree machinery to reuse the diffopt.file field to output to a file stream other than stdout, in line with the diff machinery already writing to diffopt.file. However, we might want to write something after the diff in log_tree_commit() (e.g. with the --show-linear-break option), therefore we must not let the diff machinery close the file (as per diffopt.close_file. This means that log_tree_commit() itself must override the diffopt.close_file flag and close the file, and if log_tree_commit() is called in a loop, the caller is responsible to do the same. Note: format-patch has an `--output-directory` option. Due to the fact that format-patch's options are parsed first, and that the parse-options machinery accepts uniquely abbreviated options, the diff options `--output` (and `-o`) are shadowed. Therefore close_file is not set to 1 so that cmd_format_patch() does *not* need to handle the close_file flag differently, even if it calls log_tree_commit() in a loop.
