ah so a workaround for the OP would be to hide the quote in a box so
hyphenation is back in more normal territory

\documentclass{article}

\usepackage{minted}

\begingroup
\makeatletter
\catcode`\'=\active
\gdef\minted at patch@PYGZsq at i{\gdef\PYGZsq{\mbox{'}}}
\endgroup

\begin{document}

\begin{minted}{latex}
   a-'
\end{minted}

\end{document}
