Subject: [PATCH 1/2] 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
