ActionStartPrevLinePlusMultilinePreserve

public ActionStartPrevLinePlusMultilinePreserve(String[] suffices,
                                                int cursorLine,
                                                int cursorPos,

Creates a multiline insert rule, properly preserving any text on current line.

Parameters:

suffices - the new lines to be added

cursorLine - the line on which to place the cursor

cursorPos - the character within the line string before which to place the cursor

psrvLine - the line in suffices on which to place the preserved text

Parameters:

doc - AbstractDJDocument containing the line to be indented.

reason - The reason that the indentation is taking place
