bug#21505: 24.4; Buffer order

[hoppe]

In response to the first question, I'd like this to be the "easy" request, that this behavior is only for when emacs opens and not continuously during the session. I agree, it does not need to be maintained during the session. 

Re: Tassilo Horn: I purposely showed my example with a wildcard since emacs could be given any expansion from the shell. To me it, and for my usual use case, it doesn't matter. I have a bunch of files I'd like to edit and I often miss those that are past the messages and scratch buffer. Opening the files in the order given from the command line seems very natural to me.

So to be clear, given the command run on the shell:

> emacs a c b

The buffer order should be [a,c,b,*messages*,*scratch*]. Currently the default behavior looks something like [b,c,*messages*,*scratch*, a].

The questions I asked the OP still stand.  The required feature is not
defined in sufficient detail.  If only the initial order is required,
it's probably relatively easy, but then that order is very fragile and
could easily break as soon as the user issues the first command.
