Modify Lines - remove space padding

Currently Alt+M dialog pads $(L), $(N), $(I) with spaces, e.g. if document has 100 lines, first 9 will be output as space + space + N, 10-99 as space + N, 100 - as N. Remove this space padding.

The $(0x) versions remain padded with 0.

On the second thought, let's keep it because it's easy to remove this padding but once removed it's hard to bring it back.
