[PATCH v7 3/7] shell32/autocomplete: Don't auto-append on control characters, except for ^V (paste)

[Gabriel Ivăncescu]

We must not auto-append on control characters, most notably Backspace, but
also ^X (cut) and so on. An exception is ^V, which auto-appends on Windows,
so this is needed to match Windows behavior (also needed when receiving
the ^V message directly).
