[Message part 1 (text/plain, inline)]

Hi,

I do not really agree.

Let me explain in detail.
Only comment blocks like the following were recognized as gtkdoc:
/**
 * This is the gtkdoc comment
 */

I wanted also gtkdoc styling to be applied to:
/** This should be gtkdoc comment too */

I admit, the regexp I wrote back in the day was not correctly escaped.
But I was trying to achieve comments with 3 or more asterisks would not get styled like gtkdoc comments.


Gr,
Toon
