Before this change the new partial downloads code was causing symlinks to be copied as regular files. This was because the partial isn't named .rclonelink so the local backend saves it as a normal file and renaming it to .rclonelink doesn't cause it to become a symlink. This fixes the problem by not copying .rclonelink files using the partials mechanism but reverting to the previous --inplace behaviour. This could potentially be fixed better in the future by changing the local backend Move to change files to and from symlinks depending on their name. However this was deemed too complicated for a point release. This also adds a test in the local backend. This test should ideally be in operations but it isn't easy to put it there as operations knows nothing of symlinks. Fixes #7101 See: https://forum.rclone.org/t/reggression-in-v1-63-0-links-drops-the-rclonelink-extension/39483
