If the source location is omitted or set to `null`, Dotbot will use the
basename of the destination, with a leading `.` stripped if present. This makes
the following three config files equivalent:
```yaml
- link:
~/bin/ack: ack
~/.vim: vim
~/.vimrc:
relink: true
path: vimrc
~/.zshrc:
force: true
path: zshrc

~/.vim:
~/.vimrc:
relink: true
~/.zshrc:
force: true
```
