So I think that the problem lies in the machinery that identifies donors 
and acceptors. We should allow the combination of arguments that you 
used, but it's more involved than just omitting the agument-combination 
check. Feel free to make a patch for it, or you'll have wait until I, or 
someone else, have a crack at it. I'll put it on my to-do list for 
g_hbond, but there's this thesis defence I have to prepare, so don't 
expect me to implement this over the next few weeks.

Regards,
