A recent refactor replaced the use of the totpoly local variable where it shouldn't have.

Thanks for looking at this. Could you update the commit title and the description to mention what this changes at the user-level? It isn't obvious looking at the code.

I guess this was a mistake in one of my recent refactors that used polys.size() instead of totpoly in a place where it shouldn't have?

I understand this is a bit of a cleanup (endVert and edge->v1, might as well use endVert here, but best to leave that sort of cleanup separate from fixes and functional changes.

Using BLI_listbase_count will be slower than using totpoly probably, since it's O(n)

I'm terrible at this human stuff; what would you propose I change it to?

Yeah that seems to be the case.

@HooglyBoogly I removed the unnecessary changes, leaving only the change of polys.size() to totpoly.
I moved the cleanup stuff into PR #105870.
