There's a considerable amount of documentation for string-list in
Documentation/technical/api-string-list.txt.

Perhaps we should look at migrating it into string-list.h, where it's
more likely to be found (and kept up to date). We did something similar
for strbuf.h a while back, and I think the result is much better. See
the commits in:

  git log bdfdaa4978^..d468fa2721

for an example.

The util field can be freed if 'free_util' is set when calling
string_list_clear() but yeah, in general the caller is managing that
memory especially if a complex free function is required (in the case of
allocating a struct with dynamically allocated fields to be stored in
the util feild).

Just pointing that out, and I'm happy with this and the previous patch.
