History search state is not reset with ⌃C

[JosephPecoraro]

The history search state is not reset with ^C. So if you use ^C to cancel out of a command and repeat the previous substring search you end up with unexpected results.

If your history is:

1. echo one
2. echo two

In the cases below I use [] to indicate cursor position when pushing ↑ to perform history-substring-search-up.

Current behavior:

# Cycle all the way through the history with the "echo " prefix to get to the end
$ echo []
$ echo two[]
$ echo one[]
$ echo []
$ echo []⌃C

# Type "echo " again and search again produces no results.
$ echo []
$ echo []

I expected to cycle all the way through the results again, just like before. But it seems the ⌃C did not reset the state.
