Not all .lock files are toml, only Cargo.lock

[technicalpickles]

I was setting up vim-bundler and was struggling to figure out why it kept treating my Gemfile.lock as toml, even though the package includes its own syntax and filetype. I filed tpope/vim-bundler#55 about it.

After some digging, it lead me to

filetype.nvim/lua/filetype/mappings/extensions.lua

Line 304 in b522628

["lock"] = "toml",

Compare this to filetypes.nvim:

au BufNewFile,BufRead Cargo.lock,*/.cargo/config,*/.cargo/credentials	setf toml

I disabled filetype.nvim, and it started working.
