augroup end indentation

Question

When I'm editing my vimrc, if I gg=G vim autoindents nicely except where augroup is involved

I end up with

augroup movingBackup
    au!
    au BufWritePost * call WriteBackupFile(expand("%:t"), expand("%:p:h"))
    augroup end

        augroup dotFile
            au!
            au BufWritePost *.dot :silent !start cmd /c "dot -T png %:t > %:r.png"
            augroup end

                nmap j gj
                nmap k gk

when I really want

augroup movingBackup
    au!
    au BufWritePost * call WriteBackupFile(expand("%:t"), expand("%:p:h"))
augroup end

augroup dotFile
    au!
    au BufWritePost *.dot :silent !start cmd /c "dot -T png %:t > %:r.png"
augroup end

nmap j gj
nmap k gk

You should use END instead of end for the closing augroup statement.

Apparently it's a bug (cf Carpetsmoker's comment), it should behave the same but it does not. From the documentation (:h :aug):

                        *:aug* *:augroup*
:aug[roup] {name}       Define the autocmd group name for the
                        following ":autocmd" commands.  The name "end"
                        or "END" selects the default group.
                        To avoid confusion, the name should be
                        different from existing {event} names, as this
                        most likely will not do what you intended.

Edit: I opened an issue regarding this question on the vim's github repo, and got an answer:

Although both "end" and "END" work, using "END" is recommended.

I'll change the indent script to also accept "end" (negatively) for incrementing the indent.
