* bootstrap: Sync from coreutils, as follows:

2006-10-11  Paul Eggert  <eggert@cs.ucla.edu>

* bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
variable was sometimes used without being initialized.  This
messed up the installation of the INSTALL file in some cases.

2006-10-09  Paul Eggert  <eggert@cs.ucla.edu>

* bootstrap (usage, main program, symlink_to_gnulib): Add option
--copy.  Inspired by a suggestion from Bruno Haible.

2006-10-03  Jim Meyering  <jim@meyering.net>

* bootstrap: Undo last change to this file, since now gnulib-tool
sticks with the automake default in generating dependencies.
