It's not fine with me:
  - It's not the role of any particular program to tell the user how to set
    his environment variables. I don't want firefox to tell me how to set
    G_BROKEN_FILENAMES, I don't want gnulib-tool to tell me how to set PATH.
    Programs should _obey_ the environment variables.
  - The syntactic conventions of $PATH have been like this for 30 years.
