Log:
(deregister_x_lib_dir_with_ld_so):
Rework the file replacement logic so that we are indifferent to whether
or not there are any lines in /etc/ld.so.conf that do not match
/usr/X11R6/lib, and we do not replace the file if we're not actually
changing it. Thanks to Filip Van Raemdonck and Andreas Metzler for
forcing me to think about this more carefully.

* Fix missing second argument to fgrep in deregister_x_lib_dir_with_ld_so(),
which can cause it to block, attempting to read from standard input; also
drop -q from fgrep's option list, since we actually want to do something
