It uses the same rename detection as git-diff, which computes a
similarity score. For example, try this:

  $ git init
  $ head -n 1000 /usr/share/dict/words >foo
  $ git-add foo; git-commit -m 'added file'
  $ git-mv foo bar
  $ git-status ;# shows rename because files are identical
  $ echo changes >>bar; git-add bar
  $ git-status ;# still shows rename because files are similar
  $ echo rewrite >bar; git-add bar
  $ git-status ;# now files are too dissimilar to find rename

My guess is that your changes, even though they seem small, or
preventing the rename detection from working.  If you have a very small
file, even a few changes can make the files too dissimilar.
