2523
The first mode moves the file in the filesystem and updates the
2524
inventory. The second mode only updates the inventory without
2525
touching the file on the filesystem.
2527
move uses the second mode if 'after == True' and the target is
2528
either not versioned or newly added, and present in the working tree.
2530
move uses the second mode if 'after == False' and the source is
2531
versioned but no longer in the working tree, and the target is not
2532
versioned but present in the working tree.
2534
move uses the first mode if 'after == False' and the source is

versioned and present in the working tree, and the target is not
