Error answers now are escaped when they shouldn't be.

#1004 didn't solve the issue with student answers not being escaped in the right way. Now answers are being escaped that shouldn't be.

Use the problem posted in #990 (comment), and enter an answer like r<1,-4,3,0>+s<2,2,1,8>. If that is correct, then change the numbers so it is not. The html in the answer is now protected by the change in #1004, and so you see things like < instead of <.

Now, change the line in the problem that has Context("Matrix")->flags->set(requireConstantEntries => 1); to Context("Matrix")->flags->set(requireConstantVectors => 1); (since that is what the flag was later changed to in #990). Then enter <r,-4r,3r,0>+s<2,2,18> where that is actually the correct answer for your seed, but with r in the entries of the first vector. Of course this shows up correctly.

Now if you revert #1004, then the first example is displayed correctly, but the second is not.

I believe this was fixed with #1027.
