If an active edit buffer exists for a source block, and this variable
is non-nil, then org-edit-src-code will not ask before returning to
the edit buffer, and future saves will overwrite the source block's
contents.
New customizable variable org-src-preserve-indentation, if non-nil,
prevents automatic removal of rectangular blocks of leading whitespace
in source code blocks. This is necessary when embedding python code in
an org file with a view to extracting all python blocks into a single
file (because whitespace indentation is critical in python code). The
changes in this commit also fix two bugs:
- Setting org-edit-src-content-indentation to zero resulted in an
infinite loop in org-edit-src-exit.
- Fixed width regions are defined by lines starting with a colon, with
optional leading whitespace. However, if there was any leading
whitespace, org-edit-src-exit behaved incorrectly, causing the leading
whitespace to grow.

Allow whitespace in code references. Allow the -r switch to remove the
references in the source code even when the lines are not numbered: the
labels can be explicit enough. Note that "-r -k" is the same than no
switch - as expected.
Thanks to Ulf Stegemann for bring this up.
This commit adds a new hook `org-src-mode-hook'.
The Hook run after Org switched a source code snippet to
its Emacs mode. This hook will run
- when editing a source code snippet with \"C-c '\".
- When formatting a source code snippet for export with htmlize.
You may want to use this hook for example to turn off `outline-minor-mode'
or similar things which you want to have when editing a source code file,
but which mess up the display of a snippet in Org exported files.
