Log Message:
Update from version 1.26 to 1.27.

Pkgsrc changes:
 o Remove the now-redundant cleanup of Curses.i and Curses.s
   before configuring.

Upstream changes:

New in 1.27 (Released January 20, 2009)

  Extraneous .i and .s files in 1.26 removed.  'make clean' cleans all
  .i and .s too.

  'gen' directory is replaced by gen.tar file, so CPAN doesn't index
  the stuff in there.  That directory is stuff for developing the Curses
  package, not stuff for users.
