[O] [PATCH] Ensure org-export-handle-comments protects its insertions

[Lawrence Mitchell]

* lisp/org-exp.el (org-export-handle-comments): Add the org-protected
property to the replacement string.

Although org-export-handle-comments adds the org-protected property to
the matched string, the subsequent `replace-match' call to change the
comment character does not add this property to the entire format
string.  Fix this by propertizing the entirety of the newtext argument
to replace-match.
---
I think this change makes the actual implementation match the
intention of the code, we want the replacement comment character
to be protected as well, however, I'm not sure if this breaks the
usecases in ob-tangle and the like.
