Ah... so your intended use case is using `yank-in-context` to yank inside code?
I see...

Then why limit it to `yank-in-context`?

[ I see that limiting it to `yank-in-context` means that it's limited to
  a command that already cares about the difference between
  code/comments/strings.  So there's some logic to it.  ]

It also occurred to me that it could make sense to link it to
electric-indent.
