If we do not have a string_list_init() function, maybe it is worth
mentioning how a person can use
memset(&list, 0, sizeof(struct string_list));
list.strdup_strings = 1 or 0;
too?
The previous text tried (too subtly, perhaps) to imply that with the
"clears" (for memset) and "might want to set the flag `strdup_strings`"
phrases.

Probably worth copying and pasting this code to another file and
trying it to make sure it works for the final draft.
Also, I am afraid I will not be able to send detailed reviews on
uncomplicated patches like this one in the future. It simply does not
scale (though I like for people to learn, at a certain point it
becomes faster to do things myself).
So if you can, it is best to find ways to motivate other people to
help with your work, by conveying what problems it will solve (in this
case: people might be confused about the initialization sequence; as
part of patch 3 demonstrated, the invariants regarding strdup_strings
are not being described clearly enough) and finding ways to minimize
the time other people have to spend to get it done.

Jonathan
