Indent with tabs by default (when no specific indentation settings apply)

[usagi-flow]

This tiny code change adjusts the default indentation behavior when no language-specific or user-defined setting applies.

Wait, don't run away... We're not having the tabs vs. spaces discussion!

Keep in mind we're talking about the behavior when Helix is opened for regular text files or with an empty scratch buffer:
At that moment, as a user, I expect the editor to act like a simple, "dumb editor".
At that moment I don't expect Helix to replace tabs with spaces because Helix thinks I could be programming in a language where spaces could be more important.

A simple, dumb editor, inserts a tab when I press [Tab], and a space when I press [Space].

There's many examples of default behavior in simple editors; KWrite, Notepad, Writer on Mac, ... but also Vim and Emacs (when they're not applying language-specific settings). They all insert a tab by default.

Therefore, for the sake of consistency with existing "expected" behavior, and because Helix is not an IDE at that moment, I suggest to change its default behavior.

I was going to "run away" like you said, but the argument

A simple, dumb editor, inserts a tab when I press [Tab], and a space when I press [Space].

completely convinced me. This is the correct approach! 👍

I was also ready to jump in and start protesting but this is a sound argument. My mind has been changed!

I'm convinced too!
