As far as I can tell, the variables $filenames and $filenames1 have the

I just figured out the problem. I was running this in a shell with
dircolors. Arggg!

doing 
filenames=`ls --color=no mydir`
is all I needed to do. Well ... maybe there's some better way of getting the
filenames
that's immune to any invisible codes.

Guess 1:
command ls # avoids aliases, I think?
\ls # similar
env ls # also similar

(note: I belive --color=no is default behavior, probably you have an 
alias that is adding --color=auto / --color=tty, which is why avoiding 
the alias should work)

Guess 2:
files="$( for f in mydir/* ; do echo -n "${f#mydir/} " ; done )"
# uses bash glob expansion instead of ls, probably faster to boot

Guess 3:
files="$( cd mydir ; echo * )"
