Fix for #20: Handle Windows file paths from WSL

[henning-erlandsen]

Running vagrant under WSL can confuse ruby as to how it should treat file paths. In this case it will treat the entire path as a filename, for example "C:\path\to\a\file.ext" will be parsed as

File.dirname(src) => "./"
File.basename(src) => "C:\path\to\a\file"

Replacing the back-slashes makes ruby recognize the windows path.

Thank you for this, it has fixed the plugin for me on WSL.

It's been nearly three months, @sprotheroe any chance that this will get merged?

[samuliasmala]

I can confirm it worked nicely so would be great to get this merged!

[cdausmus]

I've hit this issue too, can we get this merged please?

I've needed this too, tried this fix and worked.
Thank you.

Needed here too! Would be nice to merge that PR

I really need this merged as well. Any ideas how to use this variation until this is merged?
