A user has asked if there is a way to modify \hline to produce a wavy
line to use as an indicator that a tabular setting is suspended and
resumed, eg (use monospace to view)
\begin{tabular}{|l|c|r|}\hline
abc&d e f&3.1415926535\\
\wline[\baselineskip]\wline
xyz&q r s&2.7182818284\\hline
\end{tabular}
