    Windows: cm_GetBuffer does not need to contact file server when extended a file
    If cm_GetBuffer is being called in order to obtain a buffer to store
    data beyond the end of the existing file as known to the file server
    there is no reason to contact the file server.  Instead use the cached
    status info in order to allocate a new buffer zero initialized.
    This logic avoids triggering the FetchData bug in all file servers
    older than 1.4.12 and 1.5.65 in which the file server returns a
    large negative number (filesize - requested_offset) when a FetchData
    is received where the requested_offset is larger than the filesize.
    It also avoids unnecessary work.
