[U-Boot] Normal command line behavior?

[J.C. Wren]

I notice that when I hit return at a U-Boot > prompt, it executes the last
command again.  CONFIG_SYS_HUSH_PARSER is defined, from U-Boot
2009.08-rc1-00030-g56bdfa9-dirty.

It this is expected, it seems like a *really* bad idea.  It's cost me having
to reload 6M images at 115200 twice now.
