Bug: Plus signs in org tables are highlighted incorrectly [9.0.9 (9.0.9-82-gb862c2-elpa @ /Users/ryan/.emacs.d/elpa/org-20170814/)]

[Ryan <rct@thompsonclan.org>]

The following table is highlighted incorrectly by org-mode:

| Col1 | Col2 |
|------+------|
| +1 | +2 |
|------+------|

The region of text starting at the plus sign in "+1" and ending with the
plus sign in the following divider line is covered with a strikethrough
effect. I think any font effects (bold, italic, strikethrough, etc.)
should be limited to within a single cell.

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen. You don't know how to make a good report? See

http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.
