Changes by:	prajnoha at sourceware.org	2010-04-30 13:28:45

Modified files:
	tools          : lvmcmdline.c 

Log message:
	Don't run any complex initialisation for the "version" lvm2 command.
	
	We can use it even in read-only environment where a try to initialise
	file-based locking fails (not to mention other processing related with
	lvm2 init). Simply, we want to output the version only, nothing else.
	And this should always work.
