Basically yes - the only other concerns I have is about this +=
construct which makes the '+' character an illegal character for
environment variable names, but only when used at the end of the
variable.  This is anything but nice or consistent. Iwonder what
happens with notations like these:

	foo+=bar	-> "bar" gets appended to current value of "foo"
But what for:
	foo\+=bar
or
	foo+ = bar

?

And please see also my comments about changing the autostart
functionality for the user.

Maybe many long-term users of U-Boot don't see the current situation
as such a big problem?  I have no idea.

Best regards,
