Update to 2.7.0

Changes since 2.6.4

* fill-paragraph (M-q) now only affects comments, and correctly
  handles Haddock commentary. adaptive-fill-mode is turned off, as it
  was interfering.

* Yet more unicode symbols

* Better support for unicode encoding of haskell source files

* mdo correctly indented

* Indentation fixes, fixes to the fixes, and fixes to the fixes to the
  fixes

* New command: M-x haskell-check, calls (by default) hlint on the
  current file. Also bound to C-c C-v.

  You can also use the flymake minor mode with this.

Changes since 2.5.1

* Parser corrections for haskell-indentation and haskell-decl-scan

* haskell-indentation: Pressing tab in the rightmost position now
  moves to the leftmost, by default with a warning.

* Typo fix: One haskell-indentation variable had ended up in the
  haskell-ntation customize group.

* haskell-hoogle aliased to hoogle, haskell-hayoo aliased to hayoo

* Courtesy of Alex Ott:
  - Additional unicode symbols for font-lock-symbols: () == /= >= <= !! \ 
&& || sqrt
  - M-x haskell-hayoo search added, opens using browse-url
  - Bug-fix for inferior-haskell-type

* If haskell-indentation errors out, it now fail-safes to inserting
  a literal newline or deleting one character, for return and
  backspace respectively.

Changes since 2.4:

* haskell-indentation, a new minor mode for indentation.

Log message:
Remove obsolete @dirrm lines.

Log message:
Include editors/emacs/modules.mk instead of mk/emacs.mk.

Log message:
Import haskell-mode-2.4 as wip/haskell-mode.

This is a major mode for editing Haskell source code under GNU Emacs or
XEmacs.  It also supports running and interacting with the Hugs and GHCi
interpreters as inferior processes in an Emacs buffer.
