It is more pleasant to the eye if you remove the spaces:

    <infile some_cmd >outfile

Just like you wouldn't add spaces in the middle of '2>&1' when redirecting stderr to stdout:

    <infile some_cmd >outfile 2>&1

Mostly because if you do it doesn’t work: '2 >&1' is not the same as '2> &1' (invalid syntax) which is not the same as '2>& 1', which …is the same as '2>&1'.
