single and double-dot paths

[ezio416]

• joinpath()

  • does not work for lone single+double dots -> '.' or '..'
    • resolves to current working directory due to splitpath()
    • they do work if at the end of a path string and not alone -> 'C:/Users/..' or '/mnt/.'

• splitpath()

  • does not work for single+double dots anywhere but a single instance at the end -> 'C:/Users/../Windows' or '../usr/things' or '/Users/a/b/../..'
