Thank you so much for your help, rich. The explanation was enlightening, too. synergy2 sounds particularly intriguing... but I guess mostly because I never would've imagined it's possible, not because I can actually use it. 
I did notice that now sometimes comment links are missing the line unless I disable the new rule you created... but it seems to be less, and you can't win them all.
I, too, don't understand the decision to use some crazy table/div hybrid HTML for the theme... it can certainly be improved on.
Also, while the links are no longer cut off, they are valigned to the bottom of the cell. Should I just chalk that up as expected as well? The links are fully legible and clickable now, so it's not a huge deal.
Thanks again! I'll go cook up an appropriate user badge for you.
