ChangeLog.md open by change-log-mode

[ncaq]

I open ChangeLog.md, then major-mode is change-log-mode else markdown-mode.

This problem relation to #127.
I want to remove append of add-to-list arguments.

Expected Behavior

Emacs use markdown-mode.

Actual Behavior

Emacs use change-log-mode.

Steps to Reproduce

1. open ChangeLog.md

Software Versions

• Markdown Mode: 2.4-dev
• Emacs: 25.3.1
• OS: Gentoo Linux

I wrote workaround over an hour.

(cl-delete-if (lambda (element) (equal (cdr element) 'markdown-mode)) auto-mode-alist)
(add-to-list 'auto-mode-alist '("\\.md\\'" . markdown-mode))
(add-to-list 'auto-mode-alist '("\\.markdown\\'" . markdown-mode))

auto-mode-alist is diffcult…
I think good to markdown-mode add-to-list to first or do not add-to-list.
I want to add-to-list to first.

auto-mode-alist prefer asc element.
So, People who prefer gfm-mode should add elements to auto-mode-alist.
But, add-to-list don't add perfect equal element.
And it don't reorder list.
So, I most use cl-remove-if function.

I did not create pull request because add-to-list append argument is your change.

I have merged the PR from @raxod502 (see b92f00d), so this should be fixed now.
