Or that the function is buggy. :)

I'm tempted to say that we should probably die() when
read_tree_recursive fails. This should only happen if we fail to parse
the tree, or if our callback (save_files_dirs here) returns failure, and
the latter looks like it never happens.

Agreed, and I'm happy to see dead code go.

Minor nit: s/calulating/calculating/ in your commit message.
