Subject: dict: Fix bug in for_each iterations with no max_length limit
X-Git-Url: https://git.cworth.org/git?p=wordgame;a=commitdiff_plain;h=a26e439b57a16e31a8fb67a079cbad659c21fd39

dict: Fix bug in for_each iterations with no max_length limit

We've been using an idiom of min_length == 0, max_length == 0 to
indicate no length limit, but this has apparently been broken since
the rework of the for_each interfaces that introduced this.
