Tiny nit: this makes me wonder what the order represents --- how do
I pick which order for the refs in without to have?

I think the idea is just that 'without' doesn't have to be sorted (it's
a shame we don't have separate sorted string list and unsorted string
list types or a string_list_sorted() helper to catch bad callers early
to functions that care).  One way to say that would be

	Remove the refs listed in the unsorted string list 'without' from the
	packed-refs file.  On error, [...]

s/buffer/strbuf/, or s/The err buffer/'err'/
s/omitted/NULL/

With the Change-Id dropped, and with or without the above comment nits
addressed,
