Interesting. Which documentation is that? I can't find it in
http://mirrors.ctan.org/fonts/gentium-tug/doc/gentium.pdf.

The history of gentium-lgr.lig at
http://svn.gnu.org.ua/viewvc/gentium/trunk/gentium/source/fonts/gentium-tug/lig/gentium-lgr.lig?revision=4&view=markup
does not reveal anything either. I find it odd, though, that this file
does contain
LIGKERN commands not only for punctuation but also for boundary char. No idea
why that did not make it into the TFMs.

I can have a look what might be the reason here. Of course, in the end somebody
has to decide what ligatures should be in the font.
