During recent review of a topic, I noticed that there are a handful
of places where we misuse test_path_is_{file,directory} test helper
functions.  They are designed to be silent when the given path is
of the expected type, so

	! test_path_is_file foo

when you do not want 'foo' to be a file, while making the test pass,
does not help debugging when things go wrong.

These small patches touch the places where

	$ git grep -e '! test_path_' t/

shows hits, except for test_path_is_hidden that shares the same name
pattern but is not designed to help debugging like others.

Junio C Hamano (3):
  tests: do not negate test_path_exists
  t2021: do not negate test_path_is_dir
  test: do not negate test_path_is_* to assert absense
