Since all completions, including scope ones, are based on tags, and we
never had local tags parsed AFAIK, I'm pretty sure it never worked. But
I'd be happy to be proven wrong :)

Hum, true. I'm investigating this, but first things I found:

1) scope completion of anonymous structs/unions got "broken" since
r5563, because it made these anonymous have a non-unique name in the
whole workspace (and since scope completion is based upon var type, it
gets the completion for all who shares a name). This prehaps may be
fixable in scope completion itself to chose only one -- and the right
one :D -- parent.
However a quick & dirty "fix" is to revert r5563, but it was meant to
stop reparsing to lead to infinite increasing of the anonymous suffix.

2) if there is more than one possible candidate in the whole project for
scope completion, the first match is taken without further care (AFAICT).

However I can't tell yet why editor_prefs don't complete at all, since
it works with a resolver I wrote for debugging (e.g. replicating what I
understand tm_workspace_find_scope_members() does).
I think I gonna need understanding tm_workspace... :'(
