The above two commands are not the same.

That echo command seems to emit 79 spaces, followed by one newline (but no 
numbers at all ??)

That (my) python2 command emits 81 spaces, the four numbers, and a newline.

Try this one (fixing my off-by-one space count, as the ',' comma in print args 
emits a space of its own):

 python2 -c 'print " " * 79, 1234' | grep --color=always '[1-9]'

And try this one (fixing what I guess is your accidental omission of one space 
and  the four numbers):

echo "                                                                          
      1234"| grep --color=always '[1-9]'

I get the same results from either of the last two test cases above, with the 
red "1234" numbers
NOT appearing in an 80 wide xterm or uxterm, but appearing ok if I widen the 
terminal.
