Be aware that both approaches will misbehave if HOME is a root directory

esac
Actually, shortening /// to / is okay (it's only // that must not
unconditionally be shortened to /, due to POSIX specification and Cygwin
behavior of //), so a modified version would be:
case $HOME in
*[^/]* ) HOME=${HOME%${HOME##*[^/]}} ;;

esac
wouldn't this be better?
case "$HOME" in
/ | // ) ;;

esac
