Thank you for these patches.  Since there's been no comment on this,
I've decided to add this to core.

You've forgotten a few things:

- Add the new test file to distribution/manifest
- Add the new test to the Windows batch file
- Update the documentation to mention the new macro

I've fixed this, and I also saw that make-promise wasn't documented
anywhere (except in the discussion of delay's behaviour), so I've added
this as well.  I didn't find a good place to add this, so I decided
to add it to the part where DELAY is discussed in "The R5RS standard",
with the explicit note that this is a CHICKEN extension.

After I wrote this I noticed that we both had forgotten another thing:
- to add it to the NEWS file.

So I've done that and pushed that as well.

Cheers,
Peter
