gutteridge b6bb9bdde9 tr.1: add a "see also" xref to ctype(3) (to align with an inline 
reference), improve punctuation, etc.

XXX lines 177-191 have been commented out since they were imported in
r. 1.2 back in 1993, they should probably be re-examined, and revised
or removed.

leot 8d25f7611b Do not accept invalid octal character values (>= 0400). 
This also avoid possible stack corruption (e.g. previously `tr -s '\400'' or
similars lead to them).

Reviewed and thanks to <pgoyette>!

dholland 848d757378 Make tr -c work. Fixes PR 48113. 
When -c is in effect, scan string1 first, complement it, and then
iterate over the results while scanning string2. Otherwise, scan
string1 and string2 together as before.

christos 0ffd30a090 It is pointless to assign to the CLASS.set member and never use it again. 
Perhaps the author meant to check if it is already set and not allocated it
again to avoid memory leaks? Anyway make everything const back and delete
the unused code. Yes, this leaks the same way as before but it is
insignificant. If we want to save memory we could use bytes or even bits
instead of ints, and not allocate/initialize the same thing multiple times.
