+Subject: [PATCH] obnamlib: sftp: Add prefetch size argument
+
+Paramiko made this argument required in v1.16.  Details at
+https://github.com/paramiko/paramiko/commit/49072f3537a8981e9d448c22481a1d2b92c03643
+
+Attempt to fetch the entire file.  I'm unsure if this is the original
+intent.  If the entire file isn't to be fetched, then the prefetch() is
+probably not needed.
