C2X Proposal, merge '.' and '->' C operators

[J Decker <d3ck0r at gmail dot com>]

Here's the gist of what I would propose...
https://gist.github.com/d3x0r/f496d0032476ed8b6f980f7ed31280da

In C, there are two operators . and -> used to access members of struct and
union types. These operators are specified such that they are always paired
in usage; for example, if the left hand expression is a pointer to a struct
or union, then the operator -> MUST be used. There is no occasion where .
and -> may be interchanged, given the existing specification.

It should be very evident to the compiler whether the token before '.' or
'->' is a pointer to a struct/union or a struct/union, and just build the
appropriate output.

The source modification for the compiler is very slight, even depending on
flag_c2x(that's not it's name).  It ends up changing a lot of existing
lines, just to change their indentation; but that shouldn't really count
against 'changed lines'.

I'm sure, after 4 score and some years ('78-19) that it must surely have
come up before?  Anyone able to point me to those existing proposals?
