* Made finddesc.lua execute commands using `sh -c 'command'`, which ensures that Unix-like shell is used instead of cmd.exe
* Made finddesc.lua avoid a situation where it would end up with a double '/' in `outpath`
* Redirect output of deleting the document to null to avoid pointless "No such file or directory" errors.

* It didn't add spaces after the ## or #, which made them not work as headings in some renderers, so I fixed this.
* I then made it add newlines to make it look nicer without being rendered.
