(Removed in: 3.0)
This option enables you to tell TinyMCE to apply some source formatting to the output HTML code.
With this option set to true, line break characters are placed after and before some tags (defined in the options "indent_before" and "indent_after").
With this option set to false, the line breaks are stripped from the HTML source.
Example of usage of the apply_source_formatting option:
apply_source_formatting : true
