+Subject: [PATCH] completion: correctly do a signed comparison, to avoid a
+ segfault
+
+Bug existed since commit 30fc197b (a month ago) which changed the
+type of 'i' from int to size_t, causing the comparison to do the
+wrong thing when 'threshold' is negative.
+
+This fixes https://savannah.gnu.org/bugs/?53722.
