Not necessarily, if the directory variable would contain a (relative)
path to where the project root is.

I actually think this is better (given there is a command to add a
directory to the list of known projects), because you could also build a
project switcher on this foundation.

And if the variable is a user option (which I think it should be),
savehist shouldn't be necessary.
