Text alignment does not allow now to replace whitespace with a printable character, since it leads sometimes to weird behavior. For example, when comparing "bad man" and "batman", the deletion of d and substitution of the white-space with t has identical Levenshtein cost (two operations) than the deletion of the white-space plus the replacement of the d with a t (also two operations).
