So I suggest lslpp hardcodes /usr/bin/tr
or better again uses LC_ALL, LC_COLLATE=C etc.
to enforce working in ASCII mode.

lslpp is AIX-specific, so it can assume AIX-specific extensions to tr.

How about if we make 'tr -A' compatible with AIX practice? It would make for one 
less objection to using coreutils on AIX, and it shouldn't be hard to add.
