Adam,

<xsl:template match="br">
<!-- 1st, retrieve the block ancestor you're worried about -->
<xsl:variable name="containing-block" select="(ancestor::p|ancestor::li|ancestor::blockquote)[last()]"/>
<!-- (you'll have to extend that list to include all the possible blocks) -->
<!-- now, figure out what text nodes are actually following inside the block -->
<xsl:variable name="text-following">
<xsl:for-each select="$containing-block//text()[.=current()/following::text()">
<xsl:value-of select="."/>
</xsl:for-each>
<!-- now, include the br if there's anything there besides white space -->
<xsl:if test="normalize-space($text-following)">
<xsl:copy-of/>
</xsl:if>
</xsl:template>

(untested)

It's slow and painful, but then those <br> elements are painful too.

What do you think? I'd like to see a slick solution, too....
