I'm not comfortable with the "if possible" part of this suggestion.
Even if the user's file system supports xattrs, the tools used might
still cause nasty surprises.

For example, on this Debian box Emacs is by default set up to create
backup files by renaming.  While I'm not claiming to have looked very
closely at xattr semantics, I would guess that

  rename(file, file~)
  ... write new contents ...

would leave the user with the original file-id xattr in file~ (which
by default would be ignored by tla), and no corresponding xattr in
file.  This would be bad.
