[BusyBox] Busybox shell bugs.

[Rob Landley]

Grep from cvs is not printing filenames when given multiple arguments via 
xargs.  In the busybox source, do:

find . -name "*.c" | xargs grep bb_getopt_ulflags

Also, when using busybox ash, commands that pipe into another command do not 
get aborted when the command they're piping to exits.

Repeat the above piping into a nonexistent file:

find . -name "*.c" | xargs grep bb_getopt_ulflags | does_not_exist

Or pipe to more and then hit q at the first screen full...

I've reproduced the "tar ignoring C" thing, and am working on it...
