Tests for _autoenv_authorize. {{{

Auth file is empty.

  $ cd ../..
  $ cat $AUTOENV_AUTH_FILE

Failed authorization should keep the auth file empty.

  $ _autoenv_authorize does-not-exist
  Missing file argument for _autoenv_hash_pair!
  [1]
  $ cat $AUTOENV_AUTH_FILE

Now adding some auth pair.

  $ echo first > first
  $ _autoenv_authorize first
  $ cat $AUTOENV_AUTH_FILE
  :/tmp/cramtests-*/_autoenv_utils.t/first:271ac93c44ac198d92e706c6d6f1d84aefcfa337:1 (glob)

And a second one.

  $ echo second > second
  $ _autoenv_authorize second
  $ cat $AUTOENV_AUTH_FILE
  :/tmp/cramtests-*/_autoenv_utils.t/first:271ac93c44ac198d92e706c6d6f1d84aefcfa337:1 (glob)
  :/tmp/cramtests-*/_autoenv_utils.t/second:7bee8f3b184e1e141ff76efe369c3b8bfc50e64c:1 (glob)

And a third.

  $ echo third > third
  $ _autoenv_authorize third
  $ cat $AUTOENV_AUTH_FILE
  :/tmp/cramtests-*/_autoenv_utils.t/first:271ac93c44ac198d92e706c6d6f1d84aefcfa337:1 (glob)

  :/tmp/cramtests-*/_autoenv_utils.t/third:ad180453bf8a374a15df3e90a78c180230146a7c:1 (glob)

Re-add the second one, with the same hash.

  $ _autoenv_authorize second
  $ cat $AUTOENV_AUTH_FILE

Re-add the first one, with a new hash.
