Repeated pattern makes one wonder if a thin wrapper
xstrfmt_to(&file, "%s/%s", maildir, list.items[i].string);
that first frees the existing value and then overwrites is an
overall win. Perhaps not, as you would (1) initialize the variable
to NULL before doing a series of xstrfmt_to(), and (2) free the final
one yourself.
