2017-03-24vi: avoid touching a new file with ZZ when no editing has been doneYousong Zhou
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.

2017-03-13vi: don't touch file with :x when modified_count == 0Denys Vlasenko
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 Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2016-09-28vi: fix '' command (goto to prev context)Denys Vlasenko
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.

2015-01-07vi: fix reading of file after last lineRon Yorston
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.
