I seems to have messed up the branch.
H:\tmp\LIB-TIME-tzdb>git branch
* main
master
H:\tmp\LIB-TIME-tzdb>git checkout master
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.
H:\tmp\LIB-TIME-tzdb>git checkout main
Switched to branch 'main'
Your branch and 'origin/main' have diverged,
and have 5 and 1 different commits each, respectively.
(use "git pull" to merge the remote branch into yours)
H:\tmp\LIB-TIME-tzdb>git pull
fatal: refusing to merge unrelated histories
Have to delete the branch and start over I guess.
