Make the language specifier to "break set" actually filter the names by their language. So for

Browse Source 
instance:

break set -l c++ -r Name

will only break on C++ symbols that match Name, not ObjC or plain C symbols.  This also works
for "break set -n" and there are SB API's to pass this as well.
