Some digging in the docbook release notes suggests that this probably
changed in 1.73.0, which was released in July 2007:

* Michael(tm) Smith: synop.xsl; block.xsl; info.xsl; inline.xsl; lists.xsl;
endnotes.xsl;

Changed handling of bold and italic/underline output in manpages
output. Should be transparent to users, but...

This touches handling of all bold and italic/underline output. The
exact change is that the mode="bold" and mode="italic" utility
templates were changed to named templates. (I think maybe I've
changed it back and forth from mode to named before, so this is
maybe re-reverting it yet again).

I haven't actually tested whether we can build against 1.73.0, but that
seems like a good place to start.
