what is "the parser" exactly ?

I agree that the regular search expression in the
org-fontify-meta-lines-and-blocks-1 seems to match only one level of
src block. I am not an elisp programmer but splitting
the function in two part will allow to make it recursive (and thus to
cope with several level of nested src block) ? Well it's pure
speculation without testing...
