+#!/bin/bash
+
+# Test to demonstrate a position overlap bug.
+#
+# At one point, notmuch would index terms incorrectly in the case of
+# calling index_terms multiple times for a single field. The term
+# generator was being reset to position 0 each time. This means that
+# with text such as:
+#
+# To: a@b.c, x@y.z
+#
+# one could get a bogus match by searching for:
+#
+# To: a@y.c
+#
+# Thanks to Mark Anderson for reporting the bug, (and providing a nice,
+# minimal test case that inspired what is used here), in
+# id:3wd4o8wa7fx.fsf@testarossa.amd.com
