How do you exit vimdiff mode in vim, specifically, for Fugitive?

Question

I am using vim with the fugitive extension. It has a :Gdiff command which brings you into vimdiff mode, but what is the right/quick way to close/quit vimdiff mode?

I.e.,

Answer 1

Was using the code below based on https://stackoverflow.com/a/15113951/10999673 :

    if !exists(":Gdiffoff")
        command Gdiffoff bw! fugitive://*
    endif

but it gave me an error "E93: more than one match for ..." in a 3 way diff, so i instead used the answer from https://stackoverflow.com/a/4867969/10999673 and finally have this:

function! GetBufferList()
    return filter(range(1,bufnr('$')), 'buflisted(v:val)')
endfunction

function! GetMatchingBuffers(pattern)
    return filter(GetBufferList(), 'bufname(v:val) =~ a:pattern')
endfunction

function! WipeMatchingBuffers(pattern)
    let l:matchList = GetMatchingBuffers(a:pattern)

    let l:count = len(l:matchList)
    if l:count < 1
        echo 'No buffers found matching pattern ' . a:pattern
        return
    endif

    if l:count == 1
        let l:suffix = ''
    else
        let l:suffix = 's'
    endif

    exec 'bw ' . join(l:matchList, ' ')

    echo 'Wiped ' . l:count . ' buffer' . l:suffix . '.'
endfunction

command! -nargs=1 Gdiffoff call WipeMatchingBuffers('fugitive://')

I just tweaked, copied and pasted the code into my .vimrc
