watch:* and source:* tags should be considered as "uninteresting" tags

[bilbo]

JOSM have list of tags that are considered "uninteresting" and if primitive contains only "uninteresting tags" it is not considered to be tagged (and so for example if you delete a way, nodes used only by this way are deleted as well if they are tagged only with uninteresting tags and thus considered "untagged")

I think "watch:<username>" tags should be added to list of uninteresting tags, so when you delete some way where nodes are watched, these nodes will get deleted automatically too.

Also, while "source" is on list of uninteresting tags, more precise variants like "source:name" or "source:position" or generally "source:<something>" are not. These should be added too.

(In [3003]) fixes #4540 - watch:* and source:* tags should be considered as "uninteresting" tags

You can also supply your own list of uninteresting tags in Advanced Preferences under tags.uninteresting

Wildcards are not supported, but entries that end with ':' will match whole namespaces.
