Promptless search

[jabcross]

After reading some of the proposed ideas on the limitations of the behavior of search, find and select, I think I have arrived at an idea that solves a couple of them.

Namely, a version of search (and rsearch) that:

• works independently in each selection (like f and t)
• respects mode (will extend in select mode like most motions)
• reads the pattern directly from a given register without prompting the user
• each cursor will search for a different pattern if there are multiple values in the register (same behavior as p)

I expect it would be mostly useful with macros, heavy multicursor workflows, and in sequenced keybinds.

Any thoughts?

If there is a better place to bring this up, please let me know.
