joinpath able to handle output of splitpath

[jullit31]

It would be very handy if joinpath could "undo" splitpath, i.e.

joinpath(splitpath("/path/to/somewhere"))

should work and return "/path/to/somewhere".

You can just splat the result into joinpath:

julia> joinpath(splitpath("/path/to/somewhere")...)
"/path/to/somewhere"

We could also just allow joinpath to work on a collection of paths. In fact, that should be the core method which the varargs method calls.

@Keno Thanks! That's a lot better than the workaround I came up with.
However, I still think it would be more intuitive if what I suggested worked. (Unless, of course, there is a reason for it not to work.)

[StefanKarpinski]

The only issue would be a dispatch conflict between the varargs and container version but that would only occur in the case of a single string argument which is ok. In general since we tell people not to use splatting for this kind of thing we should be consistent and provide a non-splatting API here as well.
