Just to conclude this matter, the issue is solely a Windows
configuration issue and has nothing to do with FreeBSD (or Cygwin).
After a great deal of digging (I hate Windows), I found that changing
the Default input language from "English (United States) - United
States-International" to "English (United States) - US" turns off the
translation of quote-A to A-acute. (The difference in behaviour
between Cygwin ssh and PuTTY was due a PuTTY setting for the remote
character set being set to Latin-1.)
