Thanks I've applied all the tests and some of the changes to 'test', but not
this one:

I'm not sure I like it - and it should be a separate patch anyway (but then
there really should have been a few separate patches here...)
Maybe doing something like that is OK with an arg is given or an environment
variable is set, but I don't want to create all these log files by default.
Also, I'm begining to hate all this 'env-*' stuff. Can someone remind me
why this was a good idea?
All the symlinks definitely are ugly and bad. If each test script just
started with
source env-whatever
when they wouldn't be necessary, would they ????
Thanks,
