Patch 5.7.027
Problem:    Starting to edit a file can cause a crash.  For example when in
	    Insert mode, using CTRL-O :help abbr<Tab> to scroll the screen and
	    then <CR>, which edits a help file. (Robert Bogomip)
Solution:   Check if keep_msg is NULL before copying it.
Files:	    src/fileio.c
