bug#699: grep in eshell incorrect

[xah lee <xah@xahlee.org>]

Ok. I just did ls, and yes it forms multi columns.

However, when i do

ls | grep xyz

it doesn't produce the result eshell would. i.e. the multi column  
produced by ls seems to be a done as display formatting, not as its  
real output. I might be wrong... but i mean the bottom line is that "  
ls | grep some" have different behavior in unix shell and eshell.

Yes, it _is_ supposed to emulate a Unix shell.  But I just tried that
same pipe both on GNU/Linux and on MS-Windows, and in both cases "ls"
still forms multiple columns even in a pipe.  So I don't see anything
wrong with how Eshell's "ls" works.
