Hm. So this is documented in "The db_shell setting" at
https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch. AFAICT, the
only useful option there for my purposes is to set

db_shell = /bin/fish

After restarting sshd, this does make fish my login shell. Of course, it makes
fish the login shell for every other user on the host too, but for single-user
hosts such as mine, that works fine. Thanks.

Andrew
