inserting a new line below a comment in vim?

Question

While inserting a new line below a comment in vim, the result tends to insert a " at the start of the new line. It's probably a simple solution or reason why this is happening, but I am unable to find an exact solution.

If you’re editing a file of the vim filetype, Vim might by default insert the comment character (in Vimscript, this would be ") at the beginning of each new line you enter after a comment. As already mentioned, this is a result of Vim’s formatoptions setting.

To turn this behavior off in the current file, run

:set formatoptions-=ro

To turn it off by default, add this to your ~/.vimrc:

set formatoptions-=ro

To turn it off for Vimscript files, add this to your ~/.vimrc:

augroup filetype_vim
    autocmd!
    autocmd FileType vim setlocal formatoptions-=ro
augroup END

r and o are options which can be given to formatoptions. For the full list of possible options, run :help fo-table.
