LaTeX values pretty printer.
Still experimental. Give it a try and send us your feedback! :)
LaTeX pretty printer
This function should be used only for debugging purposes since it may change
the semantics of the input in order to create a prettier output.
In other words, running a LaTeX compiler in the output file of
renderFile fp l may
produce a different document than running it in the output of
writeFile fp (prettyLaTeX l).
You should use
renderFile unless you really need to read the LaTeX file.
