The bulk update request #2100 is pending approval.
remove alias threading (0) -> all_the_way_through (2876)
Reason: Over the last couple of months, I have been (painfully slowly) creating subtags for all_the_way_through under the root tag threading (because bolting extra words on a tag that's already 4 words long gets pretty tedious). See topic #29360 for more details. Having now gone through all posts currently tagged as ATWT, I am now planning on tying all of them together under the root tag threading, which is currently aliased to ATWT.
Since BURs can't operate on tags that have been unaliased as part of the same script, I'm submitting this one separately.
