Nope, it doesn't like that syntactically.

Nor that (I also tried finding documentation on what exactly the angle
brackets mean, but couldn't).

Actually, what I showed earlier does seem to have some weirdness with
else-if. But I finally stumbled on something even better:
- oidcmp(a, b) != 0
+ !oideq(a, b)
Because of the isomorphisms that coccinelle knows about, that catches
everything we want. Obvious ones like:
diff --git a/bisect.c b/bisect.c
index 41c56a665e..7c1d8f1a6d 100644
--- a/bisect.c
+++ b/bisect.c

+ if (!oideq(&cur->item->object.oid, current_bad_oid))
return cur;
if (previous)
return previous;
and compound conditionals like:

struct commit_list *l = xcalloc(1, sizeof(*l));
l->item = c;
and even non-if contexts, like:

}
So I think we have a winner. I'll polish that up into patches and send
it out later tonight.
