Patch to fix indent error when current line is in SRC block

[S.P.Tseng <deftsp@gmail.com>]

I add function 'org-edit-src-find-region-and-lang' to the begin of the
'org-indent-line-function'. When current line is in SRC block do nothing.

So, you can use below code to indent the whole buffer.
,----
| (defun my-iwb ()
|   "indent whole buffer"
|   (interactive)
|   (delete-trailing-whitespace)
|   (indent-region (point-min) (point-max) nil)
|   (untabify (point-min) (point-max)))
