The syntax for slices in display filters currently includes:

    [i:]     start_offset = i, end_offset = end_of_field
I propose we also allow [i-] to mean the same thing. ISTM this is more natural, since [i:j] means j is a length, while [i-j] means j is an offset, so [i-] would be a better fit to the documentation.
No replies to this, but I attach a patch to do it anyway. I had some trouble remembering if I should use [i:] or [i-] for "a slice starting at offset i and ending at the end of the field". Now either will work.
