I have just applied this after doing some testing. 

I have a couple of minor comments that can perhaps be addressed in a
follow-up patch.

If it fails to find a number going forwards in the buffer, it'd be
useful if it could look backwards too. In contrast to an editor, the
cursor is more often at the very end of the buffer in a shell.

I think that just adding zle -f vichange to the beginning of the
function it will work together with vi-repeat-change (.) which brings it
closer to ^A/^X in vim.
