This dialog allows you to set some options of comment editor.
If checked, the text from editor will be wrapped in source code to the specified length.
If checked, the following applies.
During reading source code comments to editor (on editor startup) all new lines in source code comments are ignored and replaced by spaces in comment editor. All occurrences of $EOL$ in source code are replaced by new lines in comment editor. This mainly applies when @-style comments are used. In XML comments, <para> tag is used for paragraph delimiting instead of $EOL$ macro.
The reverse process is applied when writing comments from editor to source code (OK or Apply button was pressed). Every new line in editor is replaced by $EOL$ in source code.
These options should be used carefully if you have manually formatted your source code and don't want it to be reformatted.
