Yes, it should be, but I think there will be a few user-visible fallouts
(like "--abbrev $foo" in scripts should now be "--abbrev-default $foo"
for safety).

But we are on our way to fix this, no?  IOW this warrants not a version 
bump, but an extended feature freeze/bug fix period (like Junio suggested, 
until January).

I think the resolution seems to be that we will now support "--abbrev
foo", though we didn't in the past. Because the "foo" here is optional,
the old "git log --abbrev HEAD" is ambiguous. In this case we'll see
that "HEAD" isn't a number and DWIM. But that means a script trying to
be unambiguous should use "git log --abbrev-default $foo" to make sure
that "$foo" doesn't accidentally match as a number.

So there will be user-visible changes (though I don't expect them to be
huge...there simply aren't that many variables with optional arguments).
