Creates a new comment or moves to the beginning of an existing comment, indenting it appropriately (see Set Comment Column).
If the current point is in a line already containing a comment, that comment is indented as appropriate, and the current point is moved to the beginning of the comment. An existing double semicolon comment is aligned as for a line of code. An existing triple semicolon comment or a comment starting in column 0, is not moved.
A prefix argument causes comments on the next relevant number of lines to be indented. The current point is moved down the relevant number of lines.
If characters not associated with the comment extend past the comment column, a space is added before starting the comment.
