Given the plain tex file
$\bordermatrix{&\cr 1&0\cr2&0\cr}$
\bye
I get the attached output with large delimiters with pdftex and
unstretched ones with 0.87.
(Since I compiled this myself for cygwin, and patched the format
building, it's possible that I just have things set up wrong but I
thought I'd flag it anyway)
