huh?

here are screen-shots of what it's doing on linux, which is what i expect 
and desire:
	http://smasher.org/tmp/snapshot149.png
	http://smasher.org/tmp/snapshot150.png

here's a screen-shot of modifying IFS, which i almost thought would work, 
but it makes sense that it doesn't work as above:
	http://smasher.org/tmp/snapshot151.png

the 151 screen shot shows what doesn't work. if i try the commands used in 
the 149 or 150 screen-shots on freebsd, i get the same non-results as 
shown in 151; the name of the file i'm rsyncing, and then nothing.

or this:

all of rsync's output of interest is stdout. it's mostly a bunch of 
progress updates, separated by carriage returns.
