	tools          : lvmcmdline.c 

Log message:
	Ensure --metadatacopies parameter gets interpreted based on command.
	
	Now that we have both --pvmetadatacopies and --vgmetadatacopies,
	we need to make sure --metadatacopies gets interpreted correctly.
	
	For pv commands, --metadatacopies should imply --pvmetadatacopies,
	and for vg commands, --vgmetadatacopies.
	
	Note: this will change the behavior of vgcreate with --metadatacopies
	to be a synonym for --vgmetadatacopies.  Previously, --metadatacopies
	would apply to any PVs given with vgcreate that needed an implicit
	pvcreate.  As a result, one small change is needed to one of the nightly
	tests - t-vgcreate-usage.
