Thank you both.
Pádraig, if you make that change,

   -s, --squeeze-repeats   replace each input sequence of a repeated
character\n\
-                            that is listed in SET1 with a single occurrence\n\
-                            of that character\n\
+                            that is listed in the last specified SET,\n\
+                            with a single occurrence of that character\n\

Then you should also change the preceding line, so that it no longer mentions
"input sequence", e.g.,

     -s, --squeeze-repeats   replace each sequence of a repeated character\n\

because with -s and two sets (squeezing and translating), it replaces sequences
in the post-translation stream.
