I found a few more issues:

This valid translation spec aborted:
  LANG=en_US tr '[:upper:]- ' '[:lower:]_'
This misaligned conversion spec was allowed:
  LANG=C tr 'A-Y[:lower:]' 'a-z[:upper:]'
This misaligned spec was allowed by extending the class:
  LANG=C tr '[:upper:] ' '[:lower:]'

I'll apply the attached soon.

cheers,
Pádraig.
