[Report] root/community/* tiddlers cause problems if FileSystemPaths filters are used

[pmario]

To reproduce

• Create tiddler: $:/config/FileSystemPaths
• Add filter [tag[Community]addprefix[community/]]
• Edit tiddler Community Cards
• Save -> issue

---

• Community Cards is originally part of root/community/docs/
• It is deleted there -> Issue
• It is saved at editions/tw5.com/tiddlers/community/

---

Moving root/community/ directory into an editions/_tw-shared/tiddlers/community/ has the same problem,
because $:/config/FileSystemPaths takes precedence.

---

edtions/tw5.com/_tw_shared has the same problem

eg: edtions/tw.org includes _tw_shared using tw.org/tiddlers/_tw_shared/tiddlywiki.files with this content

{
	"directories": [
		"../../../tw5.com/tiddlers/_tw_shared"
	]
}

• eg: Motovun Jack.svg has a tag: Picture
• If there is a [tag[Picture]addprefix[images/]] in FileSystemPaths and
• Motovun Jack.svg meta data is changed, it will be saved "locally"
  • This may or may not be a problem.

But deleting Motovun Jack.svg from its origin is a problem

---

Proposal

Investing a lot of time to make tw5.com work with $:/config/FileSystemPaths, I think the right thing to do is:

• Create a new flag for tiddlywiki.files named: pinFilepath
• pinFilePath takes precedence over configurations in FileSystemPaths

---

I do have a proof of concept, that I use for the FileSystemPaths experiments.

• I am not sure if it catches all edge cases
• I am not sure if it has other side effects

But it works quite well for me at the moment.

IMO this issue is slightly related to
