It looks good to me. Maybe it could more explicitely state that the
larger goal is to convert shell code in 'git-submodule.sh' to C code
in 'submodule--helper.c'. It can be guessed from the subject though.

Please add space chars around "!=" like "argc != 2".

Nit: it might be a bit simpler to define config_name as a "char *",
and then use xstrfmt() and free() instead of strbuf_addf() and
strbuf_release().
