Sorry, I sent this by accident, it was in drafts.

You explained this in the patch's message. But could there be a way that 
the list of overwritten anyway? Like when the user enables savehist-mode 
mid-session (or simply after project--list is used for the first time), 
and savehist-mode reads the histories from a saved file, overwriting the 
current session's values?

Perhaps it would be more reliable to have separate history variables 
(one for directory names, and one for project names), and construct 
their values dynamically before reading the project.
