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 indented to a minimum column.|
The indentation of comments starting in column 0 is never changed.
The indentation of a comment starting with this regexp will not be changed.
A comment anchored at the beginning of line.
A comment that starts with this regexp is indented as if it is a part of IDL code.
