The Progress 4GL language use nested comments, like

[17:57:56] <Vampire0> I don't think bemace is right
[17:58:16] <Vampire0> If a language supports nested
comments, jEdit should support it too
[17:58:51] <Vampire0> And if you have commented blocks with
/* */ and then want to comment a large block containing some
of them, then you see the need of nested comments
[17:59:21] <ezu5t> bmace is right only for languaes which do
not support nested comments
[17:59:42] <ezu5t> which may include c++ and java
[17:59:59] <ezu5t> but not progress4gl
[18:00:02] <Vampire0> Of course, but there are languages out
there, supporting nested comments
[18:00:08] <Vampire0> And for these it should work
[18:00:20] <Vampire0> In my opinion
[18:00:51] <ezu5t> right
[18:01:00] <Vampire0> k, so i will reopen it, thx

Nesting comments doesn't even make sense.  It can't be any
more commented.  Once the parser enters a comment, the only
thing its looking for is the end comment.  A '/*' inside a
comment is just more text.

Solution with DELEGATE:

put in the progress.xml 
a new Ruleset:
  <RULES SET="COMMENT" DEFAULT="COMMENT1" IGNORE_CASE="TRUE">
      <SPAN TYPE="COMMENT1" DELEGATE="COMMENT">
        <BEGIN>/*</BEGIN>
        <END>*/</END>  
      </SPAN>
  </RULES>
and in the  main Rulset you change the SPAN Tag for the
COMMENT1 Type  :
 <!-- COMMENT1   : Normal Progress comments -->
      <SPAN TYPE="COMMENT1" DELEGATE="COMMENT">
        <BEGIN>/*</BEGIN>
        <END>*/</END>  
      </SPAN>
