Perhaps the first step to resolving all this is for project-find-file to 
use a different history variable than find-file.

Which makes sense, given that one (usually) uses relative file names, 
and the other -- absolute ones.

Maybe project--read-file-absolute could continue using the current 
variable, too.

As a result, all projects will share history, for good and bad. Perhaps 
next we could do something about that, e.g. if the history iteration 
could allow pre-filtering, we could also filter out non-existing files.
