Turns out, this wasn't working because I hadn't installed the CA
certificate for the nextcloud instance.  The browser let me access the
cloud instance nevertheless, but with net use...

$ net use https://cloud.somedomain/remote.php/dav/files/corinna \
/user:corinna somepassword
System error 1244 has occurred.

As soon as I installed the certificate it started working!

$ net use https://cloud.somedomain/remote.php/dav/files/corinna \
/user:corinna somepassword
The command completed successfully.

And it started working in Cygwin with the patch removing the at-sign
prior to calling GetAddrInfoW:

$ ls -l // | grep cloud
dr-xr-xr-x 1 corinna vinschen 0 Feb 21 21:41  cloud01 DOT somedomain AT ssl

$ cd //cloud DOT somedomain AT ssl/remote.php/dav/files/corinna
$ ls | head -1
 Backup              Musik                  'Reasons to use Nextcloud.pdf'

> *PLEASE* push the patch to cut off the L'@'

Now that it works for me and I could actually test it, done.  This will
be in test release 3.6.0-0.387.g8cebbb2b42bf.

Thanks for the input in terms of Webdav.
