remove more instances of 'texttt' from jsmath output

[jhpalmieri]

Try this in the notebook with the "Typeset" box checked:

random_matrix(ZZ, 5, 5).eigenvalues()

You will see a box saying "Unknown control sequence '\texttt'". The attached patch fixes this by replacing "\texttt" with "\hbox" before processing the LaTeX string with jsMath.

This was reported on sage-support.

Attachment: trac_8633-texttt.patch.gz

Works for me (I had another case of \texttt - thank you for providing such a timely patch!) and for the given code.

Is it ready for review? The patch does not add any doctests, but I am not sure if it is possible to test such an issue in doctests. At least it does not break any existing ones.

I get the same problem on 4.4.2 with

html.table([random_matrix(ZZ, 5, 5).eigenvalues()])

even though the example in this ticket does work.

I think that the two calls to latex in sage/misc/html.py need to be changed from

latex(XXX)

to

latex(XXX).replace('\\texttt','\\hbox')

Open another ticket, cc me, and post a patch.

(Oh, and add a doctest in the patch.)
