Updating spec repo `master`
warning: inexact rename detection was skipped due to too many files.
warning: you may want to set your diff.renameLimit variable to at least 19371 and retry the command.

You need to set and unset that rename limit:

git config merge.renameLimit 999999
git config --unset merge.renameLimit
