Use 3+ dots named directories instead of aliases

[Mr-Ker]

Standards checklist:

• The PR title is descriptive.
• The PR doesn't replicate another PR which is already open.
• I have read the contribution guide and followed all the instructions.
• The code follows the code style guide detailed in the wiki.
• The code is mine or it's from somewhere with an MIT-compatible license.
• The code is efficient, to the best of my ability, and does not waste computer resources.
• The code is stable and I have tested it myself, to the best of my abilities.

Changes:

• If a directory named ... (up to 6 dots) exists then changing directory should
  lead to a change to that directory, otherwise the corresponding alias should be
  used.
