Arrrg.  Sorry about that.  Actually, my original test used a different program
(ssh) that exhibited similar behavior to echo; I was trying to simplify the test
to the bare minimum.

Nevertheless:

Nope.  If I leave CYGWIN unset, and run the Cygwin echo.exe explicitly:

d:\users\antony>c:\cygwin\bin\echo.exe hello |od -c
0000000000     h   e   l   l   o  \r  \n
0000000007
