<g> elements were previously only handled when they occurred within <abbr> tags, but they do occur elsewhere, so I've now added a new handler which shows their character description as a mouseover popup wherever they show up. The original handler for <xsl:template match="choice[child::abbr[descendant::g] and child::expan]"> has also been tweaked so that it more clearly distinguishes between the expansion of the abbreviation, and the explanation of the one or more gaiji characters which appear in it.
