Workarounds for stuck haskell repl

[d12frosted]

Following #3271

• don't move cursor back when entering normal mode in haskell REPL
• enter insert mode when switching to haskell REPL by using
  haskell-interactive-switch function

@TheBB what do you think? I thought that setting evil-move-cursor-back to nil is enough. 😄

[d12frosted]

Oh. Have I broken anything about evil?

[TheBB]

Nah, the tests are broken on develop.

[d12frosted]

Ah. Almost good to know 😄

[TheBB]

I pushed a fix. If you rebase on top of the recent develop the tests should pass.

[d12frosted]

Done! 😄

@syl20bnr should chime in on this, but I feel the advice is a no-go, just too intrusive and unexpected. The evil-move-cursor-back setting is better, but I still feel it works best as a documentation tip and not as a default. It can throw some vimmers for a loop. But... that's just my feeling.

[d12frosted]

@TheBB I see. Well I am fine with either of your decisions. Since stuck REPL is documented in the FAQ section we are already good to go. If we are not going to set evil-move-cursor-back to nil by default, then it's good idea to add this option to FAQ section as well.

As for advice... well, after I thought about it for a little more I realised that it's really not the thing to do. If you set evil-move-cursor-back to nil then there is no problems with opening REPL - you are in normal mode but the cursor is on the right place.

Update

So probably, don't merge my other PR until we decide what to do with it, so I don't spam with more PRs 😄

After some time of thinking I realised that this should be really up to user. I updated README file with tips on how to use it. So closing this PR. Thanks for your input, @TheBB!
