I've closed that bug report. Here are my comments on it.
"triangularize appears to carry out Gaussian elimination, and
is observed to yield the same thing as echelon except that
the leading coefficient isn't necessarily 1. I've updated
Matices.texi to say that. Also the description of
triangularize now mentions LU and Cholesky as other things.
Closing this report as fixed."
