Change several int variables to size_t, ssize_t, or ptrdiff_t. This should fix the bug described in CVE-2012-5667 when an input line is so long that its length cannot be stored in an int variable. This is based on NetBSD's revision which says: This change to NetBSD's version of GNU grep 2.5.1 (licenced under GPLv2) was made without direct reference to any code licenced under GPLv3.
