The original "rewrite in C" did somewhat a sloppy job while stealing code from git-write-tree. The caller pretends as if the write_tree() function would return an error code and being able to issue a sensible error message itself, but write_tree() function just calls die() and never returns an error. Worse yet, the function claims that it was running git-write-tree (which is no longer true after cherry-pick stole it).
