This PR is targeted at #3176

@JoeKar So far I only updated the docs. Please let me know if such changes make sense, so I can start implementing them.

This isn't gonna be backwards compatible, is it?

[bartekpacia]

I was thinking about it, but in the initial proposal I decided to omit this. But I definitely would like to make this change completely painless for everyone. Making anyone lose time over such a minor change would be unprofessional.

By "backward compatibility", do you mean that if ~/.config/micro/backups and ~/.config/micro/buffers exist, they should be used and whatever is in ~/.local/state/micro should be ignored?

Another option would be to copy ~/.config/micro/backups and ~/.config/micro/buffers to ~/.local/state/micro.

[dmaluka]

Dunno. Neither option seems perfect.

[JoeKar]

The backward compatibility will be a nasty thing.

Another option would be to copy ~/.config/micro/backups and ~/.config/micro/buffers to ~/.local/state/micro.

In that case you will do this with every startup, right? Maybe it's better to move it then and maintain the new location only. 🤔

Maybe it's better to move it then and maintain the new location only.

Yeah, it's also an option.

The situation where the change I'm planning to make would cause problems seems very rare: Micro would have to crash, the user would have update in the meantime, and then the backup would be missing.
