[Swan-dev] make clean is eating my testing/pluto/*/OUTPUT directories

[D. Hugh Redelmeier]

I have noticed a few times recently that my OUTPUT directories disappear.

This is very disconcerting.  Like now: I've lost what I was working on.

It seems to be "make clean".  This is bad news for me because I use "make 
clean" before I "make base".  It does NOT mean that I want OUTPUT gone.

I can see deleting OUTPUT directories on "make distclean" or whatever 
target is like that.

I suggest "make clean" go back to its old behaviour.  Strongly.

BTW a few OUTPUT directories are not deleted.  Perhaps those are for tests 
that are somehow disabled.  I haven't investigated.
