  I do not disagree.

  To do it properly would be more involved. This is semistructured
output of a group of messages and all are translated. So just
changing the structure and content of only onw message would be

  Possible solutions:
  a) Don't care. Change the one message anyway.

  b) Drop the message entirely. Output would read:
       jpeg: .
     instead of
       jpeg: . - Output directory already exists and is writable.

  c) Change all messages to something else.
       ERROR: Could not access output directory '/dir': permission denied
       ERROR: Could not use output directory '/dir': not a directory
       ERROR: Could not use output directory '/dir': not writable
       Using output direcory '/dir'

  d) Leave as is.

  Option d) is the fastest to implement and a) and b) should
also be easy. Option d) is too involved for me ATM. But if
someone else wants to implement it, I will probably apply.
