Scp: path-related bugs on windows

[giftig]

Somewhat related to #94 but fairly distinct issue: there appear to be bugs around interpreting paths when uploading via scp from a windows localhost to a linux remote host. I haven't narrowed down the root cause but I can see that slashes are sometimes being dropped and resulting in the remote path being incorrect.

e.g. an attempt to upload to /tmp/foo/bar.txt from windows resulted in the file actually being created in /tmp/foobar.txt.

Hi there

Thanks for filing this.
In fact, I haven't tried this crate on Windows yet. So there might be some unexpected behaviours.
I'll look into this issue later (maybe in one or two weeks), along with #95

BRs.
