Error messages fall into infinite loop

[godbyk]

Test case:

\documentclass{article}
\usepackage{hardwrap}
\GeneratePackageLogMacros{pkg}
\begin{document}
\makeatletter
\pkg@error{Error text.}{More error text.}
\makeatother
\end{document}

After hitting Ctrl+C, the following message is shown:

\hw@wrappedtext ->\hw@protected@newline 
                                        Error\space text.
l.11 \pkg@error{Error text.}{More error text.}

hardwrapsetup redefinitions should be localised

thanks for spotting this in testing!
