When I was trying to fix an issue with caption, I was not brave enough 
for massive changes. I do not like the original code of the function.

There are some unit tests for exporting of src blocks. Maybe the new 
option should be tested as well.

On the one hand I have no a better suggestion, but on the other hand 10 
arguments is too much for straightforward code from my point of view. 
Unsure that getting parameters in each function or passing a property 
list would not be worse however.

It reminds me a case when a colleague failed in despair trying to figure 
out what was wrong with his 15 argument fortran function. I do not 
remember exactly whether it was a missed argument or an extra one. The 
last one was assumed to be a parameter (constant) and the identifier was 
not available in debugger since compiler just substituted the number 
without creation of a symbol and it added even more confusion.

My other notes are rather loosely related to your patches. The issues 
may be postponed till someone will start a new thread for them. My hope 
is that some of them might be easily addressed so that they will not 
need separate testing.

A problem with percent sign in captions is tracked on 
updates.orgmode.org. Some environments has not fixed yet:

That time I was puzzled why the option is named "multicolumn" while only 
regular "figure" is added:

If language is added to "#+begin_example:" than the block content is 
properly fontified in the Emacs buffer. It would be great to treat such 
example similar to source block during export. When some code is not 
supposed to be executed, it is natural to use example block. I am 
curious if new functions may be reused.
