  save-cwd: reduce default dependency
  
  save-cwd generally needs only a working fchdir or a working
  getcwd(NULL,0).  If you are not worried about directories whose
  absolute name is longer than PATH_MAX, then reducing the default
  dependencies reduces the bulk for this module.
  
  However, there are cases where neither function works on Linux
  (an unreadable but searchable directory can be opened by O_SEARCH,
  except that Linux doesn't implement that yet; and Linux getcwd()
  has issues with long absolute names which glibc does not work
  around but which the full-blown getcwd module does).  So someone
  desiring a truly robust solution needs to import the 'getcwd'
  module at the same time as 'save-cwd'.
  
  * modules/save-cwd (Depends-on): Use getcwd-lgpl.
  * lib/save-cwd.c: Update comments.
  * NEWS: Document the semantic change.
