bug#49869: Revert buffer? Yes/No/Maybe

[Juri Linkov]

There is a new short keybinding to revert the current buffer -
just 3 keys: 'C-x x g'.  But then it asks for a confirmation
with 4 keys: 'y e s RET' that is even longer than the command keys.
This defeats the purpose of having the short key sequence.
Does 'C-x x g' really need a confirmation?

I propose to revert the buffer immediately after typing 'C-x x g'.
