8f3bf4f0d3 vi: avoid touching a new file with ZZ when no editing has been done 
This is the behaviour observed with standard vim and busybox vi of at
least 1.22.1.  It was changed with commit "32afd3a vi: some
simplifications" which happened before 1.23.0.

Mistyping filename on command line happens fairly often and it's better
we restore the old behaviour to avoid a few unnecessary flash writes and
sometimes efforts of debugging bugs caused by those unneeded stray
files.

e88608eae2 vi: don't touch file with :x when modified_count == 0 
Along with it, there are other changes

 - Check for uppercase X is removed as the expression will be always false and
   :X itself is another totally different command in standard vim
 - The status line will show number of written lines instead of lines requested
   by the colon command.  This is also how the standard vim is doing, though
   the difference is that '!' has to be explicitly specified in vim to allow
   partial writes

f560422fa0 Big cleanup in config help and description

Some config options are moved, even across menus.

No config option _names_ are changed.

cb810c48c0 patch: fix matching failure 
Fix matching failure when plist is advanced while checking for buffered
lines - the lines in the hunk that are about to be added should be
skipped when checking for matching context.

Also add a valid test case that fails with current busybox and is fixed

61fcc8c781 vi: fix '' command (goto to prev context) 
The '' command in vi doesn't currently work because after the first
apostrophe is read, the next character is converted to an integer
between 0 and 25 inclusive (for indexing the array of marks). The
comparison of the converted character with an apostrophe therefore never
succeeds, meaning that '' doesn't do anything.

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.

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%"
