#1 0 length files written

[James Bray]

If an error occurs reading a file from the server, a 0
length file is left on the handheld.

This is caused because updating of files on the
handheld (and vice-versa) is done directly. Before
the transaction is attempted, the local file is opened
in write mode. If the transaction fails, this file is
closed, and therefore reset to 0 bytes.

The solution is to read all files into a temporary
local file first, and then only replace the real local
file on successful retrieval of the remote file.

This also applies to files updated on the remote
machine.
