How will "ls -l" possibly work?  This is an example of the "table" 
layout you were already discussing.

I think us command-line troglodytes just have to deal with not having a 
whole lot of BiDi support.  There's simply no way any terminal emulator 
could possibly know what makes sense and what doesn't for a given line 
of text, coming from some random program.  Your "grep" could be grepping 
from a file with ANY layout, not necessarily one conducive to terminal 
layout, and so on.
