# 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
