Log Message:
Update to r8765.

pkgsrc changes:
  - use REPLACE_PERL instead of hand-rolled sed
  - use ncursesw
  - make curses selection work
  - add INSTALLATION_DIRS

upstream changes:
  Changes to support Unicode terminals. Link against ncursesw instead
  of ncurses, since the former knows how to translate ACS_ULCORNER et
  al into the right Unicode code points; also call setlocale() before
  starting up curses, so that it knows it has to.

Also closes PR pkg/37366.
