Patch 7.1.182
Problem:    When using tab pages and an argument list the session file may
	    contain wrong "next" commands. (Alexander Bluem)
Solution:   Use "argu" commands and only when needed.
Files:	    src/ex_docmd.c

You were lucky. We lived for three months in a brown paper bag in a 
septic tank. We used to have to get up at six o'clock in the morning, 
clean the bag, eat a crust of stale bread, go to work down mill for 
fourteen hours a day week in-week out. When we got home, our Dad
would thrash us to sleep with his belt!
