Hi,

I’m not subscribed to this list (or to -devel), so please reply also to my 
email when responding.

Thanks,
Liran Zvibel.

** Description:

Fix extra indent of d-mode  "else static if" statements 

The D programming language has a notion of “static if” conditionals.
The d-mode (from https://github.com/Emacs-D-Mode-Maintainers/Emacs-D-Mode.git)
requires cc-mode.
When writing “else static if” blocks, the code block is getting indented twice,
as well as all future “else static if”s that come later. This is very annoying.

This simple fix was originally suggested here: 
http://www.prowiki.org/wiki4d/wiki.cgi?EditorSupport/EmacsDMode/ElseStaticIf
The simple fix treats "static if" same as “if" that comes right after an “else".

I fixed it locally in my installed emacs long time ago, but today when 
downloading 
trunk to test 24.4 I was disappointed it was not already fixed by someone else. 
I know many D programmers that apply this change locally to their installed 
Emacs, 
hopefully not for long.

** ChangeLog

2014-07-31 Liran Zvibel <address@hidden>

        * Small cc-mode change to make sure “else static if” does not get 
        deeper and deeper indentation the same way that “else if” is treated 
        for d-mode that requires cc-mode.
