According to Prateek Asthana on 1/21/2008 10:21 PM:
| [CHAR*]         in SET2, copies of CHAR until length of SET1
| [CHAR*REPEAT]   REPEAT copies of CHAR, REPEAT octal if starting with 0

Thanks for the report; however this is not a bug.  All your examples used
a SET1 of length 1, so the length of SET2 did not have to be longer than
1; also SET2 is extended to the length of SET1 as though it implicitly
ended in *.  For an example where it matters:

$ echo test | tr tes '[a*]b'
aaba
$ echo test | tr tes '[a*1]b'
abba

Don't work too hard, make some time for fun as well!
