to_dir must exist in the inventory.
1266
If to_dir exists and is a directory, the files are moved into
1267
it, keeping their old names.
1269
Note that to_dir is only the last component of the new name;
742
1270
this doesn't change the directory.
1272
For each entry in from_paths the move mode will be determined
1275
The first mode moves the file in the filesystem and updates the
1276
inventory. The second mode only updates the inventory without
1277
touching the file on the filesystem. This is the new mode introduced
1280
move uses the second mode if 'after == True' and the target is not
1281
versioned but present in the working tree.
1283
move uses the second mode if 'after == False' and the source is
1284
versioned but no longer in the working tree, and the target is not
1285
versioned but present in the working tree.
1287
move uses the first mode if 'after == False' and the source is
1288
versioned and present in the working tree, and the target is not
1289
versioned and not present in the working tree.
1291
Everything else results in an error.
744
1293
This returns a list of (from_path, to_path) pairs for each
745
1294
entry that is moved.
