As documents that are opened read-only can not be modified anyway, we should turn off automatic saving for recovery for these documents.
Saving empty files for recovery is similarly useless and should be turned off too.
Does this help for recovery purposes? IE. is something saved in /tmp even if read only?
I'm going to assume that there is a reason for doing this. Especially for empty documents, that seems to make perfect sense.
Marking as NEW and leaving it up to you guys (Developers) to decide how to implement :)
Marking as LOW as it's not going to add a lot for the end user, just a functional addition for "behind the scenes" stuff.
Sorry for my irresponsiveness.
First, a clarification: Read-only files can now (3.6+) be edited. Thus, among read-only files, the non-saving behaviour should only apply to unmodified read-only files (as received via email, etc.).
Rationale for this change:
When LibO crashes and users have accidentally or deliberately opened any of these types of documents, LibO will try to restore them – this is useless (obviously, since there is nothing to restore). It also adds to the many windows that restoration wizard tends to open, therefore can be confusing to users. Lastly, it is also rather disappointing when a file is restored and there is no content in it at all.
Marking medium (again?), because it does have user impact.
I've sort of accepted (or tolerated with) this behaviour, but I must say that it makes LibO seem rather unpolished. In that sense too there is an impact. So, it would be a good idea to (carefully) resolve this.
Read only files cannot be edited - an example: just go to https://bugs.freedesktop.org/show_bug.cgi?id=37256, do not download but instead just directly open in LibreOffice version 4, this is technically a read only file now (as it hasn't been saved) but you cannot edit it. Multiple people complaining about this :-/
Just my two cents, as this is already NEW, moving on to more triaging :)

Would it be better to say "Don't save doc recovery info for unmodified file"?
