I don't have a strong opinion here, but it seems to me that frontend authors
are much better testing branch before it's realeased than random CVS state,
since frontends will typically work with released GDB.

And then, it's not much different if this change will be tested when it's on
6.6 branch than when it's on 6.7 branch.
