>Description:
	misc/lv causes segmentation failt in grep-mode if last argument was a nonexistent file.
	This happens only in case a nonexistent file is on last.
	
	
>How-To-Repeat:
	grep-mode lv fails:
	$ lv -g PATTERN /etc/profile /nonexistence
	(snip)
	Segmentation fault: 11 (core dumped)

	In this case, lv works fine: 	
	$ lv -g PATTERN /nonexistence /etc/profile
	/nonexistence: No such file or directory
>Fix:
	I am trying to contact the original lv author, but can't.
