ob-core: Remove LaTeX environment #+results type
* lisp/ob-core.el (org-babel-result-end): Alloow the result to end
into a LaTeX environment.
By adding latex-enviroment to the possible results types, a much
richer experience is possible for backends that can produce
LaTeX-formatted maths as their results (for example: Calc, Julia with
Latexify, Python with SymPy, Octave with symbolic). This is superior
to a LaTeX export block as LaTeX environments can be (1) rendered
inline, and (2) better used in non-LaTeX export formats (e.g. HTML
with MathJax). Without this, backends can output a LaTeX environment,
but new results will be added in front instead of replacing the
environment.
