Oh, of course I attached the wrong patch again.  Wish mu4e-compose could preview these.

Subject: [PATCH] Make narrowed subtree same size as the subtree, not 1 char
 less

Right now a narrowed subtree is one char smaller than the actual
subtree.  (org-mark-element) on a narrowed subtree will select a
region 1 char out of bounds, for example.  There doesn't seem like a
good reason for this to be the case.

* lisp/org.el (org-toggle-narrow-to-subtree):  Just
use (org-end-of-subtree) as the end of the subtree.
* testing/lisp/test-ob.el (test-ob/parse-header-args2):  Since we're no
longer subtracting the narrowed subtree size by 1, the subtree text
here is now 1 character longer.  I think this is reasonable and
shouldn't be surprising enough to ruin anyone's day.  If it isn't,
then (org-end-of-subtree) should be changed rather than org-narrow-to-subtree.
* testing/lisp/test-org-datetree.el (test-org-datetree/find-date-create):
(test-org-datetree/find-iso-week-create):  No more double
newlines between months in datetree, but this just seems like
incidental behavior more than deliberate behavior to begin with.
