C-x ' to repeat on consecutive ' like C-x e and C-x z?

[Urban Engberg]

I like the way C-x z may be repeated by consecutively hitting "z",
and the new implementation where C-x e works similarly.

Wouldn't it be natural to make C-x ' (next-error) do likewise?  I
often browse through grep matches or compilation errors by repeatedly
hitting C-x '.
