Nobody mentioned IFS, so I thought Id through my $.02 in. The following
will I think solve the problem:

	ifs_def=$IFS
	ifs_nl="\
	"
	while read in; do
		echo "$in"
		# other stuff
	IFS="$ifs_nl"
	done <t.in
	IFS="$ifs_def"

Now, Im not sure why the IFS change surrounds the redirection (my first
impulse was to have it surround the "read"), however, it works
correctly (empirically). It handles leading white space and special
characters correctly. It has the additional benefit of
working with sh, ksh, and csh.
