mode diff

[automaticgiant]

converge 0.6.0 told me

root/file.mode.terraform:
 Messages:
  "/usr/local/bin/terraform" exists
  "/usr/local/bin/terraform"'s mode is "-r-xr-xr-x" expected "-r-xr-xr-x"
 Has Changes: no
 Changes:
  /usr/local/bin/terraform: "-r-xr-xr-x" => "-r-xr-xr-x"

it's clearly mode-munging, because when i messed around with input, like 0555 vs 555, i can see the intended and unintended (respective) mode on both sides of the diff in each case, and independent ls -l $(which terraform) confirms.
