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.
