Please take a look at the resulting file with a dir/full.

I am still trying to get familiar with this code, but I am finding 
references to special handling if SAMBA detects that it is a VMS text file.

Any VMS file that is not a stream or a fixed record size file may get 
corrupted by an out-of-order transfer through SAMBA as the seek() 
function will not go to the correct place on a write.

I do not know if Samba 2.2.8 will do this, but I found some code where 
the VMS specific code was checking for text file types.

I saw a similar problem in the SAMBA 2.0.6 timeframe that I do not 
recall finding a resolution to.  I think it only involved VFC files that 
SAMBA simulates as STREAM files.

I was able to reproduce the problem back then by playing with a small 
file originally created on VMS with notepad.  My memory is a bit foggy 
on the details.
