Indenting should behave EXACTLY like Tab/Backspace

3. Indenting should behave EXACTLY like Tab/Backspace? will behave when used on a single, non-selected line.

but Tab/Backspace? on a single, non-selected line work as tab / backspace
tab - insert <tab>, backspace - delete 1 char.

Or what do you mean?

Not if you have the default configuration:
[x] Fake half tabs
[ ] Backspace through tabs
[ ] Fill tabs with spaces
Tab spacing: 8

 Step0:
 text

 Step1: hit Tab
     text
 
 Step2: hit Tab
 <------>text
 
 Step3: hit Tab
 <------>    text
 
 Step4: hit Backspace
 <------>text
 
 Step5: hit Backspace
 text

Does anyone have any idea what the fake half tabs is good for? :) I have so far only created badly indented files with it.

If anything, it shouldn't be default. It is recommended that you indent with either only tabs or only spaces, mixing them only leads to trouble.

the half-tabs are essentially support for 4-space indents in emacs-like mixed tabs mode. the number 4 is really pretty arbitrary, it just happens to be the most common case.

Half-tabs are good even in "fill tabs with spaces" mode. So, it's stable way to get 4-space indent, no matter if you use tabs or avoid them.
