+Subject: [PATCH] Fix ignore patterns in subdirectories with leading slashes
+
+Currenetly if you have an ignore file in a subdirectory "sub" with a pattern
+like
+    /ignorethis
+The directory sub/ignorethis will be ignored if you run ag from
+within sub, but it won't be ignored if you run it from sub's parent.
+that is
+
+    $ ag needle
+
+will search files in sub/ignorethis, but
+
+    $ cd sub
+    $ ag needle
+
+Will not.  This is a bug
