[Libguestfs] [PATCH] v2v: -i vmx: Allow ssh URLs to use spaces.

[Richard W.M. Jones]

In previous discussion here:

https://www.redhat.com/archives/libguestfs/2017-December/thread.html#00027

we preferred to use ssh://... URLs instead of server:/path.  However
the URL approach had the problem that the user had to replace spaces
with %20 in the paths.

However since using space gives an error, we can replace spaces with
%20 safely in code, thus removing one obstacle from users.
