Hi Eric,

Confirmed.

As David explained, it must be a bad interaction of the "src native
fontification". Solved by coming back to Org master, only applying your patch,
and staying (temporarily) in "no native fontification" mode.

Tested it. Works perfect... after, of course, defining a new environment,
such as (used for my test, after loading package =xcolor=):

#+begin_src latex
\newenvironment{RESULT}[0]%
{\color{green}}
{}
#+end_src

Only "glitch" is, when applying your patch:

#+begin_src sh
sva@MEDIACENTER:~/src/org-mode 0$ git apply 0001-wrap-results-header-argument-wraps-code-block-result.patch
0001-wrap-results-header-argument-wraps-code-block-result.patch:29: trailing whitespace.
        (cond
warning: 1 line adds whitespace errors.
#+end_src

There are, indeed, a couple of spaces and tabs after one of the 2 conds you
introduce in the patch. Why is it a problem (even if a warning only), I have
no idea?

Why not?  Because one needs first to add a environment in LaTeX?  Other reasons?

OK.

This would certainly be useful at some point in time, yes.

I vote for applying it to master.

Thanks a lot, once more!
