AHA!  Now we are getting somewhere.  I compiled dash myself and it
behaved properly.  I then tracked my problem to this Gentoo patch:
https://gitweb.gentoo.org/repo/gentoo.git/tree/app-shells/dash/files/das
h-0.5.8.1-dumb-echo.patch

So, apparently my problem is with Gentoo not dash.  Thanks for helping
me figure that out.
