The IDE has no cvs commands yet.

Just open a terminal and do

cd lazarus
cvs -z3 diff -u | gzip > laz.diff.gz

type 
  TStringText = class(TStrings)
  private
    fStr: string;
    ... 
  end;

see TStrings 
add some useful procedures like GetTextLength, GetLineBounds, InsertText,
DeleteText, ReplaceText, MoveText, SearchText, ... and override any
inherited method from TStrings that should access fStr.
