[cp-patches] FYI: Implemented GapContent.replace()

[Roman Kennke]

Yesterday I forgot to send this message. I implemented the replace() 
method in javax.swing.text.GapContent.

2005-07-21  Roman Kennke  <address@hidden>

        * javax/swing/text/GapContent.java
        (replace): New method. Replaces a chunk of the buffer with
        another chunk.
