ox-latex: Refactor `org-latex-src-block'
* lisp/ox-latex.el (org-latex-src-block): Extract the per-format logic
from `org-latex-src-block' into new dedicated functions:
+ `org-latex-src-block--verbatim'
+ `org-latex-src-block--custom'
+ `org-latex-src-block--minted'
+ `org-latex-src-block--listings'
This makes `org-latex-src-block' much less monolithic, taking it from
175 lines to 30, and I find also makes it easier to understand.
