Del/Backspace do not delete text selection in literate mode outside bird lines

[kostya-sh]

My emacs configuration contains:

(delete-selection-mode t)
(add-hook 'haskell-mode-hook 'turn-on-haskell-indentation)

In literate-haskell-mode DEL/BACKSPACE keys do not delete selected text outside bird lines but work as expected for Haskell code.

I am quite new to Emacs but I think it can be fixed by changing haskell-indentaton.el:

• haskell-indentation-delete-backward-char function to use delete-backward-char instead of delete-char
• haskell-indentation-delete-char function to use delete-forward-char instead of delete-char

@kostya-sh: is this one solved for you?

Can this be related to #388?

[kostya-sh]

The issue still exists, it looks like it is related to #388 but the pull request from #388 doesn't solve the problem.

So, grepping for offending functions:

$ grep haskell-indentation-delete *.el

shows zero results. I guess we were taling about previous version of haskell-indentation-mode. Current one tries to bind neither DEL nor BACKSPACE.

Yep, it works now. I haven't use haskell recently so I am not sure when it got fixed though.
