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

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
