Before the "---" line, we need to get the patch signed off by the
author (see Documentation/SubmittingPatches).

Would it be cleaner to make sure aregs->[gu]name is always set
(i.e. stuff "root" when it is not given)?

The coding guideline says that "git-compat-util.h" (or one of the
well-known header that includes it) should be the first file to be
included, and we already include "cache.h" as the first thing, so
I do not think you want this addition here.

The asterisk sticks to the variable name, not the type name, i.e.
const char *tar_owner

This means that upon error, the caller gets a half-filled args
structure and without any indication.

Hmph. Do we still use Python around here?
