+There is also a quirk with the macro \verb|\addvbuffer|.
+If the \verb|\addvbuffer| macro adds negative space below an argument, 
+the argument is
+vertically shifted downward by the same amount.  For example,
+compare the following constructions, 
+\verb|\fbox{gb}| and \verb|\fbox{\addvbuffer[-3pt]{gb}}|:
+\fbox{gb}\fbox{\addvbuffer[-3pt]{gb}}.
+In the latter case, the box is bottom-trimmed, but the result is shifted downward.  
+This adverse outcome can generally be overcome with a countering 
+\verb|\raisebox|,
+\fbox{gb}\fbox{\raisebox{3pt}{\addvbuffer[-3pt]{gb}}}.
+However, if the \verb|\raisebox| would otherwise place
+the new box above the baseline, the effect of the 
+\verb|\addvbuffer| on the bottom of the box is spoiled, as in the 
+comparison given by the constructions
+\verb|\fbox{\addvbuffer[-3pt]{X}}| versus 
+\verb|\fbox{\raisebox{3pt}{\addvbuffer[-3pt]{X}}}|
+which produces this result: 
+\fbox{\addvbuffer[-3pt]{X}}\fbox{\raisebox{3pt}{\addvbuffer[-3pt]{X}}}.
+Note how 3pt are not trimmed from the bottom of the second box.
+For this reason, the \verb|\raisebox| remedy has not been incorporated into the definition
+of \verb|\addvbuffer|; instead, the quirk has been allowed to stand.
