[elbe-devel] [PATCH 08/20] directories: add comment to state why setting envvars is ok at that point

[Torben Hohn]

we want to ban setting values in os.environ() from elbe.
However, at some places this can and need not be avoided.

init_directories() is called very early in elbe initialisation.
its ok here.
