[texhax] How to prevent page break in description environment item

[Alan Litchfield]

True, I did think of that.

Thank you for prompting me to take a more careful look at the problem.

Here is a solution (attribution to Ulrike Fischer):

\makeatletter
\def\mynobreakpar{\par\nobreak\@afterheading}
\makeatother



Apply as

\begin{document}

\quad

\vspace{232mm}

\begin{description}
   \item[first item] \quad{}\\
     Description of first item
   \item[second item] \quad{} \mynobreakpar{}
     Description of second item
\end{description}

\end{document}

While this does not redefine the list item, I am not certain one would 
want to make such a change in case it breaks something else. My 
preference in this case would be to resolve a local problem. That is, 
there are many more cases where you would want a subsequent list item 
paragraph to appear on a new page than for the previous paragraph(s) to 
be dragged onto it.

Regards
Alan
