Try the patch at <http://trac.sagemath.org/sage_trac/ticket/8084>.
The underscore issue is still present to some degree, mainly because
'x_2' is not valid LaTeX (as opposed to '$x_2$'). I think it looks
okay in the notebook now, but view('x_2') looks bad from the command
line. But this is to be expected, I think: from the command line,
"view" creates a file containing the string and runs LaTeX on it, so
if you pass it bad LaTeX, it will produce bad output.
Things to test before and after the patch, from the command-line and
from the notebook:
sage: view(type(factor))
sage: view(type(Sq(3))) # to make sure types with underscores in
their name look okay
sage: view('x^2') # invalid LaTeX, looks bad from the command line
sage: view('$x^2$')
sage: view('x_2') # invalide LaTeX
sage: view('$x_2$')
and the same things with "show" instead of "view". Also, probably the
same kinds of things but just evaluating the strings with the Typeset
button checked. What else should be tested?
