idlwave: Comment Indentation
4.1.3 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 indented to a
minimum column.
The indentation of comments starting in column 0 is never changed.
-- User Option: idlwave-no-change-comment
The indentation of a comment starting with this regexp will not be
changed.
-- 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.
