Re: [PATCH 01/16] tr portability fixes

We can mostly get around this by just using the bracket form
for both sets, as in:

  tr '[A-Z] '[a-z]'

in which case POSIX interpets this as "'[' becomes '['",
which is OK.

However, this doesn't work with multiple sequences, like:

  # rot13
  tr '[A-Z][a-z]' '[N-Z][A-M][n-z][a-m]'

Not that it matters a lot, but I wonder whether

   tr '[A-M][N-Z][a-m][n-z]' '[N-Z][A-M][n-z][a-m]'

would have done the trick.
