There is the same getenv() just a couple of lines above of all the if()s 
so that it covers both uses of tdir. I just though that doing the getenv() 
in both places is slightly more performing that do it all the time. But 
decided that this gain would be clearly below noise level. The I forgot to 
remove the now unneeded second getenv.
