FYI, here's what I came up with to replace the Perl rename program,
using portable POSIX shell and sed:

--8<---------------cut here---------------start------------->8---
rename_files()
(
    IFS=''
    /bin/sed -e h -e 's|[^/]*$||' -e p \
             -e g -e 's|.*/||'    -e p "$@" |
        while read -r dir && read -r old && read -r new; do
            [ x"$old" = x"$new" ] || mv -- "$dir$old" "$dir$new"
        done
)
--8<---------------cut here---------------end--------------->8---

It's smaller than the code previously used to check for the Perl rename
program.  I've pushed it to the 'master' branch, here:

If anyone sees a problem with this approach, please let me know.

      Thanks!
