Well, I should have tried it before posting.
I tried it and it ended up with big spaces but this works.

#!/bin/bash
Usage="Usage: $name file ..."
phelp()
{
echo "$name: replace spaces in filenames with underscore.
$Usage
Each file is moved to a name with the same directory component, if any,
and with a filename component that is the same as the original but with
any spaces changed to underscore."
}

name=${0##*/}

while getopts "h" opt; do
      case "$opt" in
      h)      phelp; exit 0;;
      *)      echo "$Usage" 1>&2; exit 2;;
      esac
done

shift $((OPTIND - 1))

for file; do
  filename=${file##*/}
  case "$file" in
  */*)    dirname=${file%/*} ;;
  *)    dirname=. ;;
  esac
  nf=$(echo $filename | tr "%20"  "\ " |tr -s "\ ")
##   nf=$(echo $filename | tr "\ " _)    
  newname="${dirname}/${nf}"
  if [ "$nf" != "$filename" ]; then
      mv "$file" "$newname"
      echo "$0: $file -> $newname"
  else
      echo "$0: $file not changed."
  fi
done
