jFYI, because I was just wondering why the org
.dir-locals.el sets indent-tabs-mode to nil.
Luckily Kyle wrote a good commit message:

--cut--
.dir-locals.el: Set indent-tabs-mode to nil in Elisp sources

Despite .dir-locals.el having a catchall value of t for
indent-tabs-mode, Org's Elisp files are a mix of tabs and spaces.
Emacs has used a value of nil for indent-tabs-mode since 93d4412046
(Set indent-tabs-mode to nil in (most) Elisp sources, 2015-04-15).  Do
the same.

So that clarifies it for me and I do NOT indent with tabs in the future :)
