Bug Summary and Steps to Reproduce

Bug Summary:
In C++, while some people say "anonymous namespace", it's not a thing in the standard. (The only "anonymous" thing I see is unions.) The correct wording is "unnamed namespace" ([namespace.unnamed] in the standard).

Steps to Reproduce:

1. In a C++ file with an unnamed namespace (namespace foo { int bar() { return 42; } }), put the cursor on bar and note that it says ".../{} (anonymous namespace)" in the breadcrumbs at the top.

Expected behavior:

1. put the cursor on bar and note that it says ".../{} (unnamednamespace)" in the breadcrumbs at the top. (or possibly ".../{} (unnamed)"?).

While this is a extremely pedantic, there's enough confusing wording in C++, it's best to be consistent.

I searched the vscode-cpptools project for "anonymous" but couldn't find where this string comes from :-/

Riproduci il testo del breadcrumb in un file C++ contenente un namespace senza nome, quindi traccia il punto di ingresso del breadcrumb o della visualizzazione dei simboli dell'estensione C/C++. Cerca nell'estensione e nelle sue dipendenze l'etichetta visualizzata, poiché l'issue segnala che una ricerca nel repository di "anonymous" non ha trovato nulla. Il lavoro è completato quando il breadcrumb usa il termine standard "unnamed namespace" o una forma più breve concordata.
