DOCBOOK-APPS: XSL: fix trailing "." in xref

[Jon Willeke <willeke@intersys.com>]

I'm using DocBook XML 4.0 with version 1.13 of the XSL DocBook Stylesheets.

All my xrefs have a trailing period.  For example,

    See <xref linkend="foo">, ...
    ...
    <example id="foo">
      <title>How to skin a cat</title>

generates the following HTML:

    See <a href="#foo">Example 1.</a>, ...
                               [^-- I don't want this]
    ...
    <a name="foo"></a><b>Example 1. How to skin a cat</b>

The period is put there by common/common.xsl in label.content mode.  I've
managed to kludge html/xref.xsl to strip the extra period:

66a67,68
>       <!-- *jcw+, 6/7/00: remove trailing "." -->
>         <xsl:variable name="jcw-foo">
207a210,219
>         </xsl:variable>
>         <xsl:choose>
>           <xsl:when test="substring($jcw-foo, string-length($jcw-foo),
1)='.'"
>
>             <xsl:value-of select="substring($jcw-foo, 1,
string-length($jcw-foo) - 1)"/>
>           </xsl:when>
>           <xsl:otherwise>
>             <xsl:value-of select="$jcw-foo"/>
>           </xsl:otherwise>
>         </xsl:choose>
>       <!-- *jcw-, 6/7/00 -->

I was hoping someone with more of a big-picture view of the stylesheets
could comment on this.
