Thanks.  I reordered the patches before sending, so when this one was
originally written, there was no "v" at the top-level of the function.
I think we can just drop this interior one. The point of the short "v"
is that it can be used as a temporary value for prefix matches, so I
think we can just reuse the same one.

I tried compiling with -Wshadow (which I don't usually do), but we're
not even close to compiling clean there. Some of them are legitimately
confusing (e.g., try figuring out "end" in parse_rev_note). But others
look just annoying (e.g., complaining that a local "usage" conflicts
with the global function). I don't know if we want to put effort into
being -Wshadow clean or not.
