precompiler constants in entry names show up in U10 tags list as "unspecified"

As Iain has mentioned on entries defined in triggers, a lot of experienced users combine entry names with precompiler constants. Others use these to generate unique entry names, or control overlays. In U9, these names appear in the tags list as "<$entname>_abc", so it's easy to jump to that specification. In U10, the same entries are shown in the dropdownlist as "unspecified" so they can not be used to jump to the code.
