`indent-according-to-mode` opens the help buffer for `haskell-mode-hook`

[gridaphobe]

This happens unless I turn on one of the indentation modes, but I want to use structured-haskell-mode, which recommends not turning any of them on.

Steps to reproduce:

1. emacs -Q -L . -l haskell-mode-autoloads.el examples/indent.hs
2. M-x indent-according-to-mode (or just hit TAB)

If using structured-haskell-mode, then TAB should be bound to (shm/tab) and not indent-according-to-mode...

[gridaphobe]

It is, but other commands still trigger indent-according-to-mode, and I
find this default behavior of opening a help buffer highly confusing. I
would be perfectly happy if indent-according-to-mode did nothing when none
of the indentation modes are turned on, or even better, if it fell back to
the default emacs indentation scheme.

The reason you're seeing a help buffer the first time you hit tab in haskell-mode is it's asking you to choose an indentation mode because there are several to choose from.
At the bottom of the help buffer, there's a link that will open a configuration buffer. make your selection, click 'Save and Apply', exit, and reload emacs.

Yes I know :). But I use structured-haskell-mode, which claims to conflict
with all of the regular indentation modes. So I want to leave them all
turned off.

It's not that big of a deal though anymore, since a recent update shrank
the help buffer to a small popup at the bottom of the frame, and it no
longer steals focus.

Why can't structured-haskell-mode implement indent-according-to-mode to indent the current position based on the context?
