pre-commit hook script help

I need a hook script that will either check to make sure svn:needs-lock is
set for all files or a hook script that will set svn:needs-lock for all
files.
I have the following hook script that works but only for files WITHOUT
spaces in the file name...

Could someone help me by suggestiong how I can improve the following script
or perhaps they have written one that works that I could modify.

Here is my pre-commit script:
#!/bin/bash

SVNLOOK=/usr/local/bin/svnlook
SED=/bin/sed

# Arguments passed to the script.
REPO="$1"
TXN="$2"

# Get the list of files (but not directories) that were added or whose
properties were modified.
the_files=`$SVNLOOK changed -t "$TXN" "$REPO" | $SED -n
's/^\(A\|.U\)\s*\(.*[^/]\)$/\2/p'`
for a_file in $the_files; do

    # Attempt to get the svn:needs-lock property.
    $SVNLOOK propget -t "$TXN" "$REPO" svn:needs-lock "$a_file" >/dev/null
2>&1

    # Exit and alert if an error occurred doing that.
    if [ $? -ne 0 ]; then
        echo "File $a_file doesn't have the svn:needs-lock property set."
1>&2
        echo "Repository policy dictates that all files must set the
svn:needs-lock property." 1>&2
        exit 1
    fi

done

# If we haven't exited by now, everything must be fine.
exit 0
