Consider `softtabstop`?

[ryanpcmcquen]

haskell-vim-now currently sets tabstop=2 rather than softtabstop=2. The main difference here is that softtabstop will always insert 2 spaces (even in a file that currently has tabs).

Perhaps this is the desired behavior, but I had not noticed any discussion about it in previous issues. Another difference is that using softtabstop=2 would show tabs as taking 8 spaces rather than 2 spaces (in files with real tabs).

Sure that sounds good. Happy to make it work better for people who use tabs. Want to send a pull request?

Is it better for tab users if we keep tabs in files that already have tabs (tabstop), or insist on 2 spaces no matter what (softtabstop)? I guess I'm on the fence. 😸

OK, I think using softtabstop is more consistent, but it would also be nice if we mapped Shift + Tab to insert an actual tab character:

inoremap <S-Tab> <C-V><Tab>

Where would that fit best in the file? Perhaps, here?

[begriffs]

Shift-Tab is often used in editors to tab backward.

Maybe this mapping would be good for .vimrc.local customization.

[ryanpcmcquen]

Is there another mapping that would be less confusing? Or should we just avoid all mappings?

FYI, in standard Vim, Ctrl + T inserts a Tab character.
