[GRASS5] Files left in /tmp from Init.sh

[Juillerat Philippe]

Hi

I noticed since I use GRASS 5.7 and also GRASS 6.0 cvs 2 problems (linked) 
that I don't have with GRASS 5.4

PROBLEM 1

A large number of temporary directories and files are left in the /tmp 
directory

PROBLEM 2

The MAPSET and LOCATION, when defined for a session, are not saved 
in .grassrc6 for a next session.

I realized that the problem was linked to the way I exit GRASS (I click the 
GRASS shell-window away and usually don't use the exit command) and to the 
etc/Init.sh file. The same problem appears when GRASS exit abnormally ex: 
grass60 /nonexistentlocation/mapset

PROPOSAL OF SOLUTION

Works fine on mandrake 10.1 with grass 6.0 beta2, as I am a biologist and not 
a real developer, you should look at this proposal carefuly :)

The changes are placed between #ooooooooooooooooo.
In order not to send a too long file I cut bin/init.sh at several places 
indicated with [...].

If it is not the right way to do, tell me, I will do otherwise next time.
