[PATCH 0/4] fast-import: handle empty paths better

This series addressed Dave Abraham's recent bug report [1] about using fast-import's "ls" command with an empty path. I also found a couple of other places that do not handle the empty path when it can reasonably be interpreted as meaning the root tree object, which are also fixed here.

John Keeping (4):
  t9300: document fast-import empty path issues
  fast-import: set valid mode on root tree in "ls"
  fast-import: allow ls or filecopy of the root tree
  fast-import: allow moving the root tree
