70f4320b40 vi: fix reading of file after last line 
If the :r command is used to read a file after the last line of the
buffer the last line of the buffer and the first line of the file
are joined.  An extra blank line appears at the end of the buffer.

   file 1
   file 1
   file 1file 2
   file 2
   file 2

	~
	~

The insertion point is normally at the start of the line following the
specified line.  When the specified line is the last one the next_line
function baulks at moving to the non-existent following line.

e5213cee38 vi: failure to open file is not an error when initialising buffer 
Commit 32afd3a introduced these regressions on the master branch:

Starting vi with no filename on the command line gives the status message
"'(null)' Bad address" instead of "- No file 1/1 100%".

Starting vi with a non-existent file on the command line gives the status
message "'new.txt' No such file or directory" instead of "- new.txt 1/1 100%"
