I really enjoy symmetry! If I am on channel main with clean working directory and I do:

% pijul reset --channel old_test
% pijul reset --channel main

I expect to find back the exact same state in my working dir.

Now, in main I have _checkouts/symlinkTata (and only this file in this directory).
I cannot track the symlink, which is a bug by itself (see #341).
In old_test, _checkouts doesn’t exist, so it is removed.
When switching back to main, only the known (tracked) files are put back.

Morale:

• pijul should only delete files it tracks. That implies:
• pijul shouldn’t remove non-empty directories!

I finally fixed this, sorry for the very long delay and thanks for the detailed explanation!
