Dir path bug

[martin045k]

Alternative fix to the dir path bug problem. This seemingly fixes the issue on Windows 10, though I have not tested the modifications on Linux / OS X or other Windows versions.

In essence, what these changes should do, is that in the new_command function of the driver, it performs a check to see, whether the OS is windows. If this is the case, it applies a custom formatting command (format_cmd), otherwise, it should proceed as before.

New commands:
clear_format: When parsed a string, it removes the singular . from the front if it is there, otherwise, if it is .. or more dots, it should not remove these. Then, after this, it will attempt to remove all consecutive / and \ reachable from the front and the back, which purpose is to eventually yield a string with some format where the leftmost part of the string is a folder name, and the rightmost part is also a folder name.

format_cmd: This cleans both the program's cmd path and user specified dir path with clear_format, then, if dir is a non-zero string, appends cmd path to the dir path, making sure to place a / between the two, which should be doable, since neither end or begin with a / or \. Likewise, it checks the dir path for a drive letter format, if not, then it appends ./ as would otherwise be there.

Hopefully this solves the problem, or at the very least, lets us move towards a more complete solution 🙂
