Works with some filetypes, doesn't work with others !

[pyed]

I don't understand why Vim behaves differently based on different filetypes, even though it knows them all and it knows their comments characters.

for C files, it will insert a new comment when I Enter and with "double-tap" Entering again will delete the comment, which is good.

with Python it will not insert a new comment when I Enter and with "double-tap" it's "of course" the same, which is bad.

with Rust it will insert a new comment when I Enter and with "double-tap" Entering again will not delete the comment, which is bad, and when I try passing "i_CTRL+U" it will delete the comment !! so why won't "double-tap" work when almost all what it does is passing this "i_CTRL+U" when you enter on an empty comment line ?

Doubletap never inserts comments; it only removes them. The reason that the comments aren't inserted in Python files is because the 'formatoptions' does not contain r or o. You can put set formatoptions+=ro in .vimrc to take care of that.

Still, I pushed 0ceb855 to fix a mistake that made Double-tap unable to remove the same comments in Python files.

I will look into the Rust issue now.
