Nicolas,

More patches (as you can see). Now ox.el, ob-core.el, and ob-exp.el are 
patched.

A few examples of how they render various src_<lang>[headers]{code} setups 
are also attached.

Discussion inline below.

Point taken.

Also, the user can customize org-babel-inline-result-wrap to always get 
verbatim or otherwise wrap the contents of the macro.

  `:wrap latex' results in @@latex: ... @@.

  `:results latex' results in
:     @@LaTeX:
:     <results>@@

which is a bit unsightly, but can be parsed and removed.

I have not touched
  - :RESULTS drawers
  - lists
  - tables

I appreciate your coaching/feedback.

Aaron Ecay's suggestion to use a macro was a good one. Thanks Aron.

Best,
