Well, it's an inconsistency, that has been there for years and actually
think one should not map C-C at all for exact that reason. Have you
tried letting feedkeys() return `<c-c>`? I think that might actually
work.
BTW: There is another inconsistency, that is, that ESC that comes from a
mapping execute the current commandline instead of aborting it.
