I am a big supporter of the approach to indent with tabs and align with
spaces. (Read [here][1] f.e.) Thus at some places a simple `s/ {4}/\t/g`
(replace 4 with whatever fits) is not enough and a bit more thought is
needed. Because of that there are still places where I plan to
substitute the whitespace in the future.
This patch contains exclusively whitespace changes. Check for yourself
with `git diff --ignore-all-space`.

wrap_plaintext_previews has to be disabled, otherwise bats output is
completely messed up. On the other hand I'd like to have it turned on
since it is useful when the usually pretty long file type classification
is used as preview.
