[U-Boot] Parsing of multi-line env vars broken

[Wolfgang Denk]

HI,

this is just a heads up:  the handling of multi-line environment
variables is broken in recent versions of U-Boot (and probably has
been broken for some longer time - can't tell exactly as I have a bit
of a problem to bisect across the MAKEALL / Kconfig changes):

Test case:

- Set multi-line var:

	=> setenv foo 'echo line 1
	> echo line 2
	> echo line 3'

  OK

- Print multi-line var:

	=> print foo
	foo=echo line 1
	echo line 2
	echo line 3

  OK

- Run multi-line var:

	=> run foo
	line 1

  ERROR.  Only the first line gets executed, the rest is missing.
  Only the first line gets parded by the hush shell...

Best regards,

Wolfgang Denk
