I didn't look at the code given your comments yet.  Later.

There's nothing wrong in submitting a patch file that is longer than the 
original code.  Nobody gets excited by long patch files.  They are 
applied by running a program which doesn't care how long the input is.

Preserving as much of the original code as possible makes the probability 
of new bugs smaller and helps others to compare the two versions and see 
clearly what's been changed.  IMHO, this is much more important than 
saving some net bandwidth.

Because you redirected the handle to another file.  You should cause DOS 
to flush its buffers *before* the redirection, since you don't want the 
data to end up in the wrong place.
