At first I was inclined to agree that the normalization should be re-added.
But actually that's not right either. If it was re-added, it would be possible
to do `sftp.mkdir("/does_not_exist/../somedir")` and `/somedir` would be
created. Normalization would remove "/does_not_exist/..".
So I now think that the current behavior is nearly correct, but commands
should check earlier whether the path ends with a slash, and remove it if it is
not significant for the operation. Unfortunately that depends on the operation.
In Unix:
* `mkdir foo/` is the same as `mkdir foo`, but not as `mkdir foo/.` (fails)
and `mkdir does_not_exist/../foo` fails, too.
* `ls -al foo` and `ls -al foo/` are not the same if `foo` is a symlink
pointing to a directory. The first shows information about the symlink, the
second lists the directory contents. (As does `ls -al cfg2/.`)
So fixing the problem reported needs to be done much more carefully.
