Subject: [PATCH 2/2] 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.
