Yes, we're using tabs to line up code that is multicolumn (typically the 
first column is code, the second comments).  Admittedly the code is not 
consistent in this area.

I'd prefer a different style, where there's a comment on one line and 
code on the next, and where there are no tabs, but now's not a good time 
to change styles.
