Runtime file updates.
updated for version 7.4.051
Problem:    Syntax highlighting a Yaml file causes a crash. (Blake Preston)
Solution:   Copy the pim structure before calling addstate() to avoid it
	    becoming invalide when the state list is reallocated.

updated for version 7.4.052
Problem:    With 'fo' set to "a2" inserting a space in the first column may
	    cause the cursor to jump to the previous line.
Solution:   Handle the case when there is no comment leader properly. (Tor
	    Perkins)  Also fix that cursor is in the wrong place when spaces
	    get replaced with a Tab.
