How can I soft wrap the gundo preview?

Question

As the title. Basically I want to apply set linebreak to the gundo window.

Answer 1

Try this:

augroup MyGundo
    au!
    au BufWinEnter __Gundo_Preview__ :setl linebreak wrap
augroup end

Answer 2

Before you get better answer, you can go to /autoload/gundo.vim (or wherever it is), there should be two functions GundoSettingsGraph() and GundoSettingsPreview() (depends on which you desire to change), and there you can change setlocal nowrap to setlocal wrap.
