and then hope you don't ever need to pushd/popd a directory with a
semicolon in it's name :)

if you want to get super paranoid, you can quote the individual
directories and then store them as a space seperated list.  i wrote
about something similar a few months back[1][2] in the context of
positional parameters, but i think it's the same basic problem.
