Highlighting comments

[H.Seldon]

Is it possible to indicate a comment line only if the comment indicater is the first (or first non-whitespace) character(s) on the line? If the comment indicater is not the first non-whitespace character(s) on the line, it would be treated normally. Thanks for your help.

Not at the moment. I may add something in a later version.
