When performing rename refactoring (one of the more common refactorings, I
would imagine), if there are strings/comments containing the current name
(be it method/field/class name), the refactoring 'tool window' shows up and offers
to exclude some/all entries as appropriate. Excluding any items has no effect.
This bug, reported as issue IDEADEV-12251, was fixed by Eugene V. for the
6.5 build line, but is not available in the 6.0.x builds.
Please, this is a common enough refactoring to warrant us having it fixed until
the 6.5 EAP starts... JB: let us have it.
