vim modify my file automatically in babun of win10

[persuez]

Describe the bug
vim modify my file automatically in babun of win10
I log in my VPS ubuntu machine with ssh. My host enviroment is win 10, babun. Just give an example.

1. echo 123 > asd
2. vim asd

Now, I find the content of asd automatically becomes 122.

cat asd ==> 123

It seems VIM automatically minus 1 of the last integer of my file. Also, my vim is just compiled, and does not have any configure files.

To Reproduce
Detailed steps to reproduce the behavior:

1. download source code after 8.2.0936(included) version
2. change dir to vim
3. ./configure --with-features=huge --enable-multibyte --enable-rubyinterp=yes --enable-python3interp=yes --with-python3-config-dir=$(python3-config --configdir) --enable-perlinterp=yes --enable-luainterp=yes --enable-gui=gtk2 --enable-cscope --prefix=/usr/local
4. make -j4
5. sudo make install
6. just vim asd, I found content of asd becomes 122.

Expected behavior
A clear and concise description of what you expected to happen.

Environment (please complete the following information):

• win10 babun, only babun will occurs

This usually means your terminal setup is incorrect, and the terminal sends CTRL-X to Vim at some point. This is the command to decrement a number.
Check your value for $TERM or 'term'.

Thank you for reminding me. I check $TERM and 'term', they are both xterm-256color.

echo $TERM ==> xterm-256color
in vim: echo &term ==> xterm-256color

But versions below 8.2.0936 do not have this problem.

This can happen when you set $TERM to xterm on a non-xterm-compatible terminal.

What does :echo v:termresponse show?
Does it still happen when you add set t_RV= in your .vimrc?

Thanks very much!

:echo v:termresponse ==> ^[[>77;10103;0c

When I set t_RV= in my .vimrc, it behaves normally. Extremely grateful. When setting $TERM to xterm on a non-xterm-compatible terminal, the terminal sends CTRL-X to Vim at some point?

babun is using mintty, isn't? I am not sure what $TERM should be set for babun. Also, it looks like babun is discontinued

[k-takata]

Ah, I didn't know that.
The above v:termresponse means that it is using mintty 1.1.3.
The latest mintty is 3.5.0 (^[[>77;30500;1300c), so 1.1.3 is really old.
