Note that to_dir is only the last component of the new name;
742
1274
this doesn't change the directory.
1276
For each entry in from_paths the move mode will be determined
1279
The first mode moves the file in the filesystem and updates the
1280
inventory. The second mode only updates the inventory without
1281
touching the file on the filesystem. This is the new mode introduced
1284
move uses the second mode if 'after == True' and the target is not
1285
versioned but present in the working tree.
1287
move uses the second mode if 'after == False' and the source is
1288
versioned but no longer in the working tree, and the target is not
1289
versioned but present in the working tree.
1291
move uses the first mode if 'after == False' and the source is
1292
versioned and present in the working tree, and the target is not
1293
versioned and not present in the working tree.
1295
Everything else results in an error.
744
1297
This returns a list of (from_path, to_path) pairs for each
745
1298
entry that is moved.
