+% The ctabbing environment is a centered tabbing environment suitable for
+% displaying program fragments.  The vertical spacing is exactly like that
+% for normal text in a center environment.  This is achieved by setting
+% \@minipagetrue to fool \tabbing into thinking that it starts a minipage
+% and should therefore avoid all vertical space at the top.  (Note that any
+% space at all would defeat the \vtop command in \ctabbing.)  The
+% \vskip-\lastskip and \prevdepth saving commands avoid extra space after
+% \endtabbing
