[U-Boot-Users] U-Boot, hush and pipes

Greetings

I've been digging into the hush parser and finding, what appear to be, 
odd things.

Obviously masses of the hush functionality has been removed using the 
__U_BOOT__ #define but some bits that are left seem to be not relevant 
to the bootloader environment. I'm particularly confused by the pipe 
operators '&' and '|' and how they are used in u-boot. Is this just a 
mistake? or am I (as usual) missing something...

A quick pass with gcc -E -D__U_BOOT__ is most revealing :-))
