Hello,

Here is a MWE:

1. With point on the "** Foo" section, running C-c C-e C-s h o, will
result in noweb-duplicate-bug.html with the <<some_snippet>> block
expanded only once, as expected.

2. But with point on the "* Foo Included" section, running the same
C-c C-e C-s h o, will result in foo_included.html with the
<<some_snippet>> block expanded twice! It seems like the Noweb
expansion happens first as usual, and then again when parsing
#+include (which shouldn't happen?).
