    window: Fix cmd_with_count's formatting when sizeof(long) != 8
    
    On architectures where `sizeof(long)` != 8, "%" PRId64 will read junk from
    memory.  This was seen on various Debian builds where
    test/functional/legacy/close_count_spec.lua would fail due to `1<C-w>c`
    emitting an error like `E488: Trailing characters: close-87944975647104`.
    
    Changing the `Prenum` parameter to int64_t ensures it is safe to use
    `"%" PRId64`, and make another small step towards removal of the use of
    `long`.
