Thank you very much for this expression that would have taken me weeks 
to come up with...

You are right that I want to include spaces in an element only if the 
space was formerly between instances of the same element, so I have 
expanded the conditional expression as follows (sorry for the mangled 
indentation):

<xsl:template match="e">
  <xsl:copy>
    <xsl:for-each-group select="node()"
      group-adjacent="if (. instance of element()) then name(.) else
        (if (name(preceding-sibling::*[1]) eq 
name(following-sibling::*[1]))
        then name(preceding-sibling::*[1]) else 'space_outside')">
      <xsl:element name="name(current-group()[1])">
        <xsl:apply-templates  select="current-group()/text()"/>
      </xsl:element>
    </xsl:for-each-group>
  </xsl:copy>
</xsl:template>

So far I haven't been able to test if it works because I don't know how 
to dynamically set the "new" element's name in xsl:element from the 
element which is the "leader" of the current group. Am I going the wrong 
way about joining instances of the same element type?

To recall, I want to transform this

<e><x>x</x> <a>a1</a> <a>a2</a> <b>b</b> <c>c1</c> <c>c2</c> <a>a3</a></e>

into this:

<e><x>x</x> <a>a1 a2</a> <b>b</b> <c>c1 c2</c> <a>a3</a></e>
