Do not add "1" to identifier name when using "Rename identifier"

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Select identifier in code
2. Invoke "Rename identifier" dialog (F2)
3. New identifier name is filled as <old_name>+"1"

What is the expected output? What do you see instead?
3. New identifier name should stay as <old_name>

What version of the product are you using? On what operating system?
Latest trunk

Please provide any additional information below.
"Rename identifier" is mostly used to give some meaningful name
(and I guess in most cases - meaningful names do not end with "1") 

Here is required change:
