[O] Strange behavior: a comma is inserted before each star

[zariskij]

Hi,

I encounter a strange behavior of org-edit-special.

Whenever I have a line starting with * in org-edit-special buffer, 
org-mode automatically inserts a comma before * in the original 
org file.

For instance, if I type into org-edit-special buffer:
/**
 * a brief descripion
 * end
 */

After saving it, in the corresponding source block in the org file, 
it will appearas

/**
 ,* a brief descripion
 ,* end
 ,*/

This affects all source languages.
