incorrect line breaking of pmatrix

Created by: pzinn

with line breaking on, if I try to typeset a matrix with \begin{pmatrix}...\end{pmatrix} that's just a bit too wide for the window, the right parenthesis will appear all alone on the next line. (this happens both if surrounded with \[ \] or \( \), though it is worse in the former case since the right parenthesis sits in the middle of the window) can this behavior be prevented?
