Comment Indentation
-------------------

   In IDL, lines starting with a `;' are called _comment lines_.
Comment lines are indented as follows:

`;;;'   The indentation of lines starting with three semicolons remains
        unchanged.
`;;'    Lines starting with two semicolons are indented like the
        surrounding code.
`;'     Lines starting with a single semicolon are indent to a minimum
        column.

The indentation of comments starting in column 0 is never changed.

 - User Option: idlwave-no-change-comment

 - User Option: idlwave-begin-line-comment
     A comment anchored at the beginning of line.

 - User Option: idlwave-code-comment
     A comment that starts with this regexp is indented as if it is a
     part of IDL code.
