\subsection{Tab character as a special}

In \LaTeX{} News~38, we described the extension of \cs{verb}, etc., to cover
the tab character as equivalent to a space. We have now added tabs to the
standard list of characters covered by \cs{dospecials}. This allows them to
be used in for example a \texttt{v}~specification document command without
additional steps.
