- create content named "test" in a (any) language
- create content named "test" in language neutral
the alias "test" will be assigned to both content items.
In path_pathauto_is_alias_reserved the current code makes sure that a localised alias does not interfere with any language neutral alias, which is fine.
however, it should check if _any_ alias exists when creating language neutral content.
Patch will follow
(there is some similarity between this and D6 issuelike comment #25)
