Blank file buffer named "scheme" opened when using netrw "scheme://host//file" syntax

[paulreimer]

With a recent version of netrw installed, this plugin causes multiple buffers to be opened when using a command e.g.
vim scp://some.validhost.com//path/to/file.txt

which opens a blank buffer with name "scp" as the first buffer, and the expected netrw buffer editing "/path/to/file.txt" on remote host some.validhost.com as the second buffer.

I assume any version combination of netrw/file-line manifests this issue, but for reference I am using version v153 of netrw, and SHA a1381d0 for file-line.
