ctrl-y doesn't do anything

[pyluyten]

yes it should "yank previously inserted text" (vim vanilla binding for C-a).

This way

• this is consitent or at least good mnemonic with readline C-y
• this binding which is shadowed by "C-a beginning of line" revives

That's a good point, but I don't really want to shadow the built-in <C-Y>, which imho is much more useful than the built-in <C-A>.

Updated https://github.com/tpope/vim-rsi/pull/17 , which maps <c-u> and <c-y> in cmdline-mode only.
