[bug #29358] segmentation fault in isdir1 with grep-2.6.1

[Javier Villavicencio]

Follow-up Comment #5, bug #29358 (project grep):

Try this little patch to exclude.c:

--- grep-2.6.1/lib/exclude.c.orig
+++ grep-2.6.1/lib/exclude.c
@@ -342,7 +342,7 @@
     {
       char const *pattern = exclude[i].pattern;
       int options = exclude[i].options;
-      if (excluded != exclude_fnmatch (pattern, f, options))
+      if (exclude_fnmatch (pattern, f, options))
         return !excluded;
     }
   return excluded;

If I got the logic right, then exclude_fnmatch() should return !excluded on
string match, not depending on if EXCLUDE_INCLUDE was set.
