#10455: Multiple adjacent [caption] tags in post body produce incorrect output

--------------------------+-------------------------------------------------
 Somewhere between WP 2.7.1 and 2.8.1, the support for multiple adjacent
 "[caption]" tags in a post body became broken.

 For example, I could enter the following code into the post textbox when
 creating a post in 2.7.x:


 {{{
 [caption id="attachment_437" align="alignnone" width="100"
 caption="DESCRIPTION OF MY FIRST IMAGE HERE"]<a
 href="(...)Img_001.jpg"><img src="(...)Img_001-100x150.jpg"
 alt="DESCRIPTION OF MY FIRST IMAGE HERE" title="DESCRIPTION OF MY FIRST
 IMAGE HERE" width="100" height="150" class="size-thumbnail wp-image-437"
 /></a>[/caption][caption id="attachment_435" align="alignnone" width="100"
 caption="DESCRIPTION OF MY SECOND IMAGE HERE"]<a
 href="(...)Img_002.jpg"><img src="(...)Img_002.jpg" alt="DESCRIPTION OF MY
 SECOND IMAGE HERE" title="DESCRIPTION OF MY SECOND IMAGE HERE" width="100"
 height="150" class="size-thumbnail wp-image-435" /></a>[/caption]
 }}}


 In 2.7.x, this outputs two DIV sections, each containing the appropriate
 image and corresponding caption.

 Under 2.8.x, the first DIV section (containing Img_001) is output
 properly, but the entire caption block for the section caption (with
 Img_002) is output as plaintext in the post (including the literal text
 "[caption]") and no fancy DIV is output for this section.

 This issue seemingly corrects itself if one inserts a space between the
 first "/caption" closing tag and the subsequent "caption" opening tag.

 For the original message thread, see

 (Please excuse the lack of wordwrap in this issue--I couldn't figure out
 how to keep Trac from mangling the excerpt above without sticking it in a
 code block, but then everything else in the post gets un-wordwrapped.)
