{- .git-annex/ moved to a git-annex branch.
-
- Strategy:
-
- * Create the git-annex branch.
- * Find each location log file in .git-annex/, and inject its content
- into the git-annex branch, unioning with any content already in
- there. (in passing, this deals with the semi transition that left
- some location logs hashed two different ways; both are found and
- merged).
- * Also inject remote.log, trust.log, and uuid.log.
- * git rm -rf .git-annex
- * Remove stuff that used to be needed in .gitattributes.
- * Commit changes.
