From afcb6ac83d8854f8cc271bb4e933836c9d4f1d3b Mon Sep 17 00:00:00 2001 From: John Keeping Date: Sun, 3 Feb 2013 14:37:11 +0000 Subject: [PATCH] builtin/apply: tighten (dis)similarity index parsing This was prompted by an incorrect warning issued by clang [1], and a suggestion by Linus to restrict the range to check for values greater than INT_MAX since these will give bogus output after casting to int. In fact the (dis)similarity index is a percentage, so reject values greater than 100.
