Subject: Tangling does not detect src blocks with capital BEGIN_SRC/END_SRC when case-fold-search nil

When tangling a file whose source code blocks have capitalized BEGIN_SRC and
END_SRC (as produced by <s-TAB for instance), org-babel-tangle will not
detect the source code blocks when case-fold-search is nil.
The variable org-babel-src-block-regexp has the begin_src and end_src in
lower
case, and neither the code generated by the macro org-babel-map-src-blocks
(in
ob-core.el) nor its caller org-babel-tangle-collect-blocks (in
ob-tangle.el) set
case-fold-search dynamically to make this regex match the capitalized
blocks in
org-babel-map-src-blocks.
I've included a minimal sample file below, but it's pretty simple to
reproduce
with Emacs -q. I also included a simple patch to ob-core.el (in
org-babel-map-src-blocks)
that I tested quickly, in case it helps.
For reference, I'm running org 8.2.10 and GNU Emacs 24.4.1 on Mac OS X
10.7.5.

### Small example
The source code block is not detected by =org-babel-tangle= when
=case-fold-search= is nil. Then change the begin/end to lower case.
#+BEGIN_SRC R
matrix(c(1:9), ncol=3)
#+END_SRC
#+RESULTS:
| 1 | 4 | 7 |
| 2 | 5 | 8 |
| 3 | 6 | 9 |
See =org-babel-src-block-regexp=, =org-babel-map-src-blocks=, and its
caller
=org-babel-tangle-collect-blocks=.
#+PROPERTY: header-args :tangle yes :comments org
# Local Variables:
# org-confirm-babel-evaluate: nil
# End:
### Quick patch (only tested quickly)
