Given a relative file path that:
- Doesn't exist, relative to the open file/buffer (default-directory),
- Doesn't exist, relative to the project root,
- Doesn't satisfy any of the other rules in ffap-alist,
- Contains more than one segment (forward slashes),
The +lookup/file command will walk the file tree from default-directory
to the project root to search for the path, so given:
project
└── src
├── a
│ └── a.h
└── b
└── b.h
This command, run on 'b/b.h' in a/a.h, will open b/b.h (but 'b.h' alone
won't work, which is intended, to reduce false positives).
