Today I refiled a headline that was part of a tree using inherited tags:

* topic1                               :tag1:
** headline1
** headline2
* topic2

If I refile headline1 to another file... the tag "tag1" is not on it
anymore...

I am not sure if the best way to handle such cases is to add the tag by hand
and then refile it
... or if it could also be an option to apply all inherited tags to it while
refiling.
