This is not a new issue with this patch, but I think strbuf_init()
at the location of filling done like this is a bad idea. If the
caller gave you an errbuf that is pre-filled with something, we'd
leak memory and lose information. It only makes sense to _init() if
the caller gave us an uninitialized garbage (or a strbuf that has
just been initialized and is empty).
The existing callers seem to do STRBUF_INIT before passing it to
this function, so we probably should not do strbuf_init() here (and
other two places in this function) and simply add to it.

Break line after pipe "|", not before, and lose the backslash. You
do not need to over-indent the command on the downstream of the
pipe, i.e.
awk ... |
xargs -n1 git -C ... &&
Same comment applies elsewhere in this patch, not limited to this file.

Make it a habit not to add dashed options after real arguments, i.e.
sort -u fetched_types
> + echo commit >unique_types.expected &&
> + test_cmp unique_types.observed unique_types.expected &&
Always compare "expect" with "actual", not in the reverse order, i.e.
test_cmp expect actual
not
test_cmp actual expect
This is important because test_cmp reports failures by showing you
an output of "diff expect actual" and from "sh t5616-part*.sh -v"
you can see what additional/excess things were produced by the test
over what is expected, prefixed with "+", and what your code failed
to produce are shown prefixed with "-".
Thanks.
