Unicode character for last item in directory

[ivov]

The Unicode character for the last item in a directory should be different.

You are currently using BOX DRAWINGS LIGHT VERTICAL AND RIGHT for the last item, but it might be more aesthetically pleasing to use BOX DRAWINGS LIGHT UP AND RIGHT or other L-shaped symbol that fits.

Example:

├── client
├── config
├── db
├── docs
├── services
├── utils
└── tests     # different character for last item
