+Subject: [PATCH] fix strverscmp comparison of digit sequence with non-digits
+
+the rule that longest digit sequence not beginning with a zero is
+greater only applies when both sequences being compared are
+non-degenerate. this is spelled out explicitly in the man page, which
+may be deemed authoritative for this nonstandard function: "If one or
+both of these is empty, then return what strcmp(3) would have
+returned..."
+
+we were wrongly treating any sequence of digits not beginning with a
+zero as greater than a non-digit in the other string.
