227 Translation occurs if __-d__ is not given and both SET1
228 and SET2 appear. __-t__ may be used only when
229 translating. SET2 is extended to length of SET1 by repeating
230 its last character as necessary. Excess characters of SET2
231 are ignored. Only [[:lower:] and [[:upper:] are guaranteed to
232 expand in ascending order; used in SET2 while translating,
233 they may only be used in pairs to specify case conversion.
234 __-s__ uses SET1 if not translating nor deleting; else
235 squeezing uses SET2 and occurs after translation or
236 deletion.
