I think we should have a good plan for how to handle these things.

If linespec can't be language-independent, then IMO it should be calling
methods on struct language_defn.  The current approach of examining the
current_language is quite bad.  (And just to be clear, C++ is probably
the worst offender here right now.)

There is a comment saying this is for C++ and Java.
How about checking explicitly for those and nothing else?
