Remarks

DeleteWhitespace removes white (empty) space around the edit point or TextSelection without first copying the text to the clipboard. If Direction is vsWhitespaceOptionsHorizontal, then DeleteWhitespace deletes spaces and tab characters on both sides of the edit point to the beginning and end of the edit point's line, or until a character that is not white space is encountered. If Direction is vsWhitespaceOptionsVertical, then DeleteWhitespace deletes blank lines on both sides of the edit point to the beginning and end of the document, or until a line that is not blank is encountered. If Direction is vsWhitespaceOptionsVertical, and the current line is not blank, then this method does nothing.
