If the answer is, as I expect, "there can't be" I suggest changing the design to put some character or different color to the link instead of showing (1) e.g.
Your basis for suggesting to change it to something else makes sense, but the (1) adds something that a star or different colour doesn't indicate:
It clearly communicates that one thing is pending here.
A fancy star would make me wonder why there's a fancy star (do I get bonus points for editing this post?). A different colour link would make me wonder why the other links aren't also coloured, like links normally are. There are a lot of ways to distinguish the link, but...
In internet lingo, everyone nowadays understands that if there is something with a (1) beside it, there is one thingy of some kind waiting there for them - whatever that thingy is.
You understand what this means:
And you understand what this is:
So when you see this:
... if you don't already immediately understand what the (1) is probably for, once you click it, you'll understand pretty quickly why you're being showed a pending edit dialog: not because there's someone else out to collect the bonus star points, but because there's one edit pending.
The fact there's never going to be a (2) is beside the point, when the (1)'s purpose is just to make this clear communication that there's a single edit waiting.
