Provide control over stripping of leading/trailing blank lines from code blocks
* org-src.el (org-src-strip-leading-and-trailing-blank-lines):
New variable allowing prevention of automatic stripping of
leading and trailing blank lines when exiting edit buffer.
(org-edit-src-exit): Respect value of
`org-src-strip-leading-and-trailing-blank-lines'
(org-src-native-tab-command-maybe): Bind
`org-src-strip-leading-and-trailing-blank-lines' to nil during
this function.
