Allow removing pages without their subpages

[freezingDaniel]

say one creates 3 wiki entries: a a/b a/c

Filestructure:

├── a
│   ├── b
│   └── b.md
└── a.md

Removing the file a.md always removes the directory including b.md and c.md.

• Desirable behaviour would be to restore the "Page Index" (delete a.md) with an option to remove subpages (a, a.md, b and b.md)

Hey @freezingDaniel, I put this is on my list of "advanced tasks" ("special tasks?") that I want to add. Thanks for bringing this up!
