Code cleanup: no unnecessary tabs, space and final dots

```Smalltalk
cms := CompiledMethod allInstances select: [:each |
each package ifNil: [ false ] ifNotNil: [:p |
	p name beginsWith: 'Grease' ]].

cms do: [:cm |
     ((RBRefactoryChangeFactory instance)
             addMethodSource: (ReMethodSourceCleaner clean: cm sourceCode) in: cm origin) execute ]
```
