It used to be that the code couldn't recurse, so the indentation level could be known statically, so it made sense to just hard-code it in the output. However, since 315a84f9aa ("subtree: use commits before rejoins for splits", 2018-09-28), it can now recurse, and the debug log is misleading. So fix that. Indent according to $indent.
