The patch used to remove 'new' (since 2017) mouse behavior in Vim, which
is applied only if user vimrc (~/.vimrc) doesn't exist. The patch
removal puts the behavior new behavior back.
Block copying with new mouse behavior is done by Shift+(mark the text
with mouse). For pasting in Vim enter insert mode and press
Shift+Insert, or for pasting in other terminal click on middle mouse
button.
The new behavior can be bypassed by creating user .vimrc or setting
skip_defaults_vim, see ':help defaults.vim' in Vim.
