There is already support for doing this in transport/ftp/,
the has_append attribute.  If the server doesn't support APPE at all
we fall back to this.  Apparently we have not yet encountered a server
that has an append but where it doesn't work properly.  You could
fairly easily check the location config stack for a new variable
ftp.disable_append and then turn that on.  It would be at least worth

If it's true, as it seems, that the problem is the server is not
read-after-write coherent with itself on a single file, I don't know
why PUT would be any more coherent than APPE....
