Message:

This patch avoids useless invocations of `cat <file> |' where the second
process in the pipe can more efficiently read its input file itself.
It replaces also some grep'+sed' commands by an unique `sed' command.
This patch also improves readability of shell commands by
replacing \" by ' where possible.
This patch instructs mondo to say DVD' instead of CD' when appropriate.
This patch forces growisofs to use speed=1 for DVD burning. In my
experience, DVD burning time is only a small part of the total backup
time so this should not make a big difference in backup time, but
a big one in reliability of mondo. On my installation, without
the option `speed=1', mondo/growisofs is unable to burn a DVD. With
the option `speed=1', mondo works.
