+% We typeset each line of the verbatim in an \hbox, so we can handle
+% tabs.  The \global is in case the verbatim line starts with an accent,
+% or some other command that starts with a begin-group.  Otherwise, the
+% entire \verbbox would disappear at the corresponding end-group, before
+% it is typeset.  Meanwhile, we can't have nested verbatim commands
+% (can we?), so the \global won't be overwriting itself.
