Okay, I think I see now.  I installed your package version 1.0-8 in
R-devel (to be 2.9.0), and the ?TallyLake man page looks fine to me in
text mode, looks slightly funny in HTML (with the labels one line above
the thing they're describing).  But to me it looks better in the new
HTML than version 1.0-7 looked in 2.8.1:  in that version, there was no
attempt to line up the descriptions to a common left margin, so they
tended to be confused with the thing they were describing.

So I'm not sure what you'd really like to see in the output.  Can you
describe it again?
