[mythtv] C++ style

[Daniel Thor Kristjansson]

Classes are the real reason to prefer pre-increment over post-increment,
with integers the compiler will figure it out. There is also a backward
compatibility reason for it. In old school C ++i is defined as a
pre-increment and i++ is defined as "whatever is fastest" so there is
no actual post-increment in C. Many compilers including gcc support it
as a post-increment because that's less surprising, but you might not
want to depend on that.

As for indentation, I've just written this bit of emacs lisp...

(defconst myth-c-style
  '((c-basic-offset . 4)
    (c-comment-only-line-offset . 0)
    (c-hanging-braces-alist     . ((substatement-open before after)))
    (c-offsets-alist . ((topmost-intro        . 0)
			(substatement         . +)
			(substatement-open    . 0)
			(case-label           . +)
			(access-label         . -)
			(inclass              . ++)
			(inline-open          . 0)
			))
  )
)

(c-add-style "myth" myth-c-style t)

You can put it in your .emacs and then load it with
M-x set-c-style <CR> myth <CR>
OR, add this to your .emacs to make it the default

(add-hook 'c-mode-common-hook
	  (function
           (lambda ()
             (c-set-style "myth")
	     )
	   )

]I'm sure others will point this out - but you can overload operators in C++;
]so the "INC a register" seems a bit narrowminded to me.
