Document relation between `joinPath` and `</>`

[andreasabel]

I would expect that joinPath[a,b] behaves exactly like a </> b (aka combine a b). Unfortunately, the documentation does not enlighten me on the relationship between joinPath and combine. Is joinPath just a fold using the monoid mempty = ""; mappend = combine?

I would have consulted the source code to clarify my question, but see #81.

Please document the relationship between joinPath and combine.

Cloning and grepping the git repo, I find joinPath = foldr combine "". This should be in the docs.

Perfectly reasonable, and also your remark about sources in #81. Note the library is transitioning ownership through #79, so I will wait for the next maintainer to respond properly.
