It would seem to me that unexpand is okay.

You will have to help us out here.  We can't see into your system.
What is the content of your /etc/fstab file?  Is it possible to
provide one line out of your file that illustrates how this does not
work?  Perhaps pipe that one line through od -c so that we know for
sure what and where the whitespace is?  (Mailers have been notoriously
broken without regards to whitespace and I fear it won't survive a
mailing correctly.)
