To not treat files like 'vimrc-tips.txt' as Vim Script files

Question

There is a line in defaults.vim that enables Vim Script syntax for any .txt file with vimrc in its filename (for example, vimrc-tips.txt):

au BufNewFile,BufRead *vimrc*           call s:StarSetf('vim')

I want to replace *vimrc* with *vimrc or maybe even with a regular expression that will allow only the period or underscore as the first character.

For this, if understnad correctly, I need to disable the original autocommand first.

I tried to disable it with

" see https://stackoverflow.com/questions/25829710
augroup standard
  autocmd!
  autocmd BufNewFile,BufRead *vimrc* setlocal setfiletype disabled
augroup END

The idea is that this should disable treating files like vimrc-tips.txt as Vim Script files, but at the same time this should not disable syntax for _vimrc, .vimrc, or any other files (for example, foo.md or bar.js).

But this doesn't disable syntax for files like vimrc-tips.txt, and even worse when I open such a file, there is a message:

Press ENTER or type command to continue

How this should be fixed?

Answer 1

1. The line in question is in $VIMRUNTIME/filetype.vim, not in defaults.vim.

2. You can override it by creating the following file:

   ~/.vim/ftdetect/vimtxt.vim
   

   with this content:

   autocmd BufNewFile,BufRead *vimrc*.txt setfiletype text
   

Note that the autocommand in the linked answer is broken.
