Comment(by jhpalmieri):
Here's a new patch. In addition to the changes listed earlier, this:
1. rewrites {{{list_function}}} etc. These were a little broken before
(e.g., putting {{{\sage{range(10)}}}} in a %latex cell should have
produced a list with each number on a different line, but it didn't;
putting {{{\sage{range(100)}}}} did put each number on a different line,
which looks horrible). Now lists and tuples are typeset with all of their
entries on a single line. This is I think what you would expect: if you
ask to typeset {{{[2,3,5,7]}}}, then you expect the list to be typeset in
the obvious way. (This is only in the notebook; the command-line
behavior is unchanged.)
2. it slightly changes {{{bool_function}}} -- changes {{{\rm blah}}} to
{{{\mathrm{blah}}}}
3. the command {{{_run_latex_on_file}}} now takes arguments "png" (whether
to produce a png file) and "do_in_background". It tries to check whether
a dvi file was created correctly by processing it with dvipng (if dvipng
is present). If something goes wrong, it calls dvips and ps2pdf. (It
doesn't just call pdflatex, because some packages, like pstricks, don't
work with pdflatex.)
4. Unfortunately, lists are now typeset all-in-one: if any part of the
list contains jsmath avoidance text, then the whole thing turns into a png
file. This is partly because I couldn't write the code cleanly to deal
with all of the cases (lists, tuples, nesting, etc.), and partly for speed
issues: if A and B each require jsmath avoidance, for example, then
{{{view([A, ZZ, B])}}} would run two separate latex processes, and this
seemed slow on the machines I was using.
