Installed, with a few alterations:

- project--expand-file-name -> project--transplant-file-name (seems more 
explicit for understanding)
- The new option renamed to project-file-history-behavior with values t 
or 'relativize. I thought about removing it, but after all, the change 
is a bit exotic, so there's bound to be people who would want to disable 
it. And the new name is also more extensible (extra behaviors I could 
think of by now: 'relativize-when-exists or 'separate -- the latter 
could mean to use separate history var other than file-name-history). No 
hurry to implement any of those, though.
- project-or-external-find-file needs some special handling of the 
relativization when external file names are chosen. Better solutions 
welcome.
- Announcement in NEWS. :-)
