I typically don't, but unless it becomes very difficult to make in-tree 
builds work, I don't see any reason to not allow them.

The following changes should fix the problems you were seeing.

I see now why the out of source tree builds are not affected.  The rm -f 
commands would attempt to remove the files from the build tree and they 
don't exist there.

I also found how the README file was being deleted even though it never 
appeared to be explicitly deleted.  The maintainer-clean target for the 
doxyhtml directory was to blame.

I've tested the maintainer-clean target in a source tree build and it 
seems to work properly now with the changesets I've checked in over the 
last few days.

Sorry for the disruption.

I'll be working on improving the way that we handle generated files 
next.  I'll try to prevent rebuilding everything just because the 
Makefile or a module.mk file is touched.
