Seems like a good candidate for merger. Only one question in each. Or should it be handled with a simple re-tag?
Small mergers like this should just be done with a manual retag (which I've done). It's when you start to get boatloads of them that a mod should get involved and to a mass retag. Basically, if a manual retag is going to be a big pain or if it's going to clutter up the front page with a bunch of bumped questions request a mod do it.
Shouldn't every tag merge become a tag synonym as well?
