[issue18222] os.path.abspath should accept multiple path parts and join them

[Łukasz Langa]

Łukasz Langa added the comment:

Would you expect to make the following also accept a sequence of path elements?

- normpath, realpath, relpath
- dirname
- exists, lexists
- expanduser, expandvars
- isdir, isfile, islink
- getsize, etc.

I agree with R. David's sentiment. Moreover, relpath takes an optional second argument which would make this change backward incompatible.
