I wouldn't say it's simple.  The best that I can come up with is this 
(note: untested), perhaps there is a more elegant solution:

<xsl:template match="break">
 <!-- locate the positions of all following breaks, appending a comma 
after each -->
 <xsl:variable name="following-breaks">
   <xsl:for-each select="following-sibling::*">
     <xsl:if test="self::break"><xsl:value-of 
select="position()"/>,</xsl:if>
   </xsl:for-each>
 </xsl:variable>
  <!-- extract the position of the first break following sibling -->
 <xsl:variable name="first-break" select="number(substring-before 
($following-breaks, ','))"/>
 <!-- don't do any copies if the next break occurs immediately after us -->
 <xsl:if test="$first-break > 1">
     <p>
     <!-- copy all elements in between us -->
     <xsl:copy-of select="following-sibling::*[position() < 
$first-break]"/>
     </p>
  </xsl:if>
</xsl:template>
