The workflow I've mentioned in comment #8 is far from being intuitive to the
end user, so I propose to add the following behavior to digikam:

When user performs some change (delete/move/rename/something else?) in tags for
the tag assigned to some files display a dialog like this:
-------------------------------------------------
You have requested to rename/move tag "/People/Alice" into "/People/Bob".
"/People/Alice" is currently assigned to 42 files.
Do you want to update these files metadata or just the Digikam database?

| Update database only |
| Update database and files |
| Cancel |

[ ] Remember my decision
-------------------------------------------------
(in case of tag deletion the wording in the first line is a little bit
different)

A new (drop-down 3-value list) option can be added under
"Settings->Metadata->Behavior->Common Metadata Actions", which will control the
above dialog:

When changing properties of a tag assigned to files:
- update database only
- update database and files
- ask me
With default to "ask me".

When user uncheck the option "Save image tags as "Keywords" tags in metadata
embedded in files" the new option (the proposed one) can be grayed out and the
dialog won't be displayed at all, since the user don't want to touch tags in
file's metadata at all.
