feat: In tree view, the branch child contents should line up with the parent's first symbol

[acid-bong]

Expected behaviour: like tree has it -- the vertical bar descends right from the first character

.config/nixos/pkgs
├── default.nix
├── desktop-scripts
│   ├── default.nix
│   ├── sqrt.sh
│   └── tp-toggle.sh
├── lilex-nerdfont
│   └── default.nix
└── nf
    └── default.nix

4 directories, 6 files

Actual behaviour: the vertical bar starts one column before the word start (the same with icons and without)

.config/nixos/pkgs
├── default.nix
├── desktop-scripts
│  ├── default.nix
│  ├── sqrt.sh
│  └── tp-toggle.sh
├── lilex-nerdfont
│  └── default.nix
└── nf
   └── default.nix

Proposal: make it look like in the tree output
