I am getting unwanted
<p> paragraph and
<br /> tags when adding an explicit excerpt to a post (I mean when I add the excerpt in the post editor's optional excerpt field).
I don't see any of those tags in the optional excerpt field when editing it, but the excerpt includes them once it is published.
In "Writing Settings" I have unchecked:
- Convert emoticons like :-) and :-P to graphics on display
- WordPress should correct invalidly nested XHTML automatically
WP releases I'm using: 2.6.5 and 2.8.5
