I would like to unconditionally remove the startup echo area message
because I do not like noise and repetition.

ATM I use this form:

    (defadvice display-startup-echo-area-message (around my-disable activate))

I do not like advising undocumented, internal functions.

Off topic:

I don't want to use inhibit-startup-echo-area-message via setq in my
init.el because my init.el is just a bootstrapping stub that loads my
real configuration files.  This indirection is necessary for my
autocompile implementation and initialisation structurization.  Forms
like (setq inhibit-startup-echo-area-message ...)  do not belong in my
user-init-file.

I share the same Emacs configuration between multiple machines and user
accounts.  When setting up a new environment, I would like to clone my
configuration repository, symlink the dir to ~/.emacs.d and get started.
Remembering to add a setq inhibit-startup-echo-area-message form
violates my zeroconf policy and screws with my vc.

I would like to keep my emacs configuration independent of the user name
I am using.  I think the two are should have no influence on each other.

I am not arguing in favour of removing that strangeness.  It just does
not work for me.  This is why I am proposing to add another value
option.  I think my use case is not that much out of the ordinary.

Stefan, incase I share my emacs configuration I will personally make
sure that the other side knows about the -q switch and C-h C-a.  Not
that this will help much, but I will do that...
