Currently, Ctrl-W removes path components, which are split on "/={,}'\""
It would be nice if we could (optionally or otherwise) add ":" to that list.
The concrete use case I have is ssh addresses such as
git clone git@github.com:fish-shell/fish-shell
It would be nice if two taps of Ctrl-W produced git clone git@github.com:, ready for specifying a different repository. Currently, it produces git clone .
