Fix handling of file renames

Both `:file` and `:saveas` rename the current file.

`:file` does not write the newly named file to disk, and keeps the same
buffer.  It fires a single `BufFilePre` / `BufFilePost` pair of
autocommands:

    `BufFilePre`     buffer
    `BufFilePost`    buffer

`:saveas` does write the newly named file to disk, in a new buffer.  It
fires two pairs of `BufFilePre` / `BufFilePost` autocommands:

    `BufFilePre`     original buffer
    `BufFilePre`     new buffer
    `BufFilePost`    original buffer
    `BufFilePost`    new buffer

In both cases the cached path needs to be cleared.

See #860, #551.
Fixes #865.
