Sorry for the confusion :(

What is stated in the documentation is the *Scintilla* default, not ta's
default. I understand this could be a particularly bad source of
confusion, but in the context where you would adjust these settings,
namely in themes, I think it makes sense. For example:

     -- Inside themes/light/buffer.lua
     -- ...
     buffer.tab_width = 2

If you were to call Adeptsense's show_apidoc() on tab_width, you would see
the default as being 8, but it is being overridden to 2.

A counter argument could be made that if I updated the documentation to
use all of ta's default values, then a user creating a new theme might be
awfully confused when they assume the default tab_width is 2 and then
wonder why it's 8 when they don't explicitly set it to 2...

It's a compromise. init.lua cannot be executed every time a buffer is
opened to set buffer settings. The purpose of init.lua is for user
initialization scripts. I needed a way to have custom buffer and view
settings that could be executed every time a buffer/view is opened and
that's where the "theme" concept comes from. I think the manual
documentation on Themes makes this clear, but please give feedback if it
is not.
