Julia: joinpath() doesn't add path separator between drive and directory

[GregPlowman]

On Windows, Julia v0.5.0

julia> joinpath("C:", "Temp")
"C:Temp"

[vtjnash]

That's the correct path. It's a relative path from C: to Temp via the current working directory of C: (which may be accessible as ENV["=C"])

So what's the correct way of doing this? We should add an example to the docstring for Windows.

There's a note explaining what

joinpath("C:", "Temp")

actually represents in the docstring for joinpath

[StefanKarpinski]

So what's the correct way of doing this?

Turning two relative paths into an absolute path just isn't something joinpath does. This is like asking why joinpath("foo", "bar") doesn't produce the absolute path /foo/bar and since it doesn't, how does one get joinpath to produce an absolute path. The answer is: you don't, you get an absolute some other way.
