[PATCH 0/6] git worktree move/remove

[Nguyễn Thái Ngọc Duy]

This version is the same as nd/worktree-move but with the recursive
directory copy code removed. We rely on rename() to move directories.

Nguyễn Thái Ngọc Duy (6):
  worktree.c: add validate_worktree()
  worktree.c: add update_worktree_location()
  worktree move: new command
  worktree move: accept destination as directory
  worktree move: refuse to move worktrees with submodules
  worktree remove: new command

[PATCH 1/6] worktree.c: add validate_worktree()

[Nguyễn Thái Ngọc Duy]

This function is later used by "worktree move" and "worktree remove"
to ensure that we have a good connection between the repository and
the worktree. For example, if a worktree is moved manually, the
worktree location recorded in $GIT_DIR/worktrees/.../gitdir is
incorrect and we should not move that one.

[PATCH 3/6] worktree move: new command

[Nguyễn Thái Ngọc Duy]

There are two options to move the main worktree, but both have
complications, so it's not implemented yet. Anyway the options are:

 - convert the main worktree to a linked one and move it away, leave the
   git repository where it is. The repo essentially becomes bare after
   this move.

 - move the repository with the main worktree. The tricky part is make
   sure all file descriptors to the repository are closed, or it may
   fail on Windows.

[PATCH 4/6] worktree move: accept destination as directory

[Nguyễn Thái Ngọc Duy]

Similar to "mv a b/", which is actually "mv a b/a", we extract basename
of source worktree and create a directory of the same name at
destination if dst path is a directory.

[PATCH 5/6] worktree move: refuse to move worktrees with submodules

[Nguyễn Thái Ngọc Duy]

Submodules contains .git files with relative paths. After a worktree
move, these files need to be updated or they may point to nowhere.

This is a bandage patch to make sure "worktree move" don't break
people's worktrees by accident. When .git file update code is in
place, this validate_no_submodules() could be removed.
