Log message:
	Fix a bug in lvm_dump.sh checks for lvm/dmsetup binaries quote the
	invocations a bit more (although i'm fairly sure there are still
	quotes missing somewhere due to the eval in log).

 Version 2.02.29 -
 ==================================
+  Fix a bug in lvm_dump.sh checks for lvm/dmsetup binaries.
   Refactor lvcreate stripe and mirror parameter validation.
   All tools: print --help output to stdout, not stderr.
   After a diagnostic, suggest --help, rather than printing all --help output.
