add backtracking functionality to search; when we find a partial but incomplete match, we want to start looking for a match from ('idx + 1'), where 'idx' is the index we started this failed search at.

handle edge cases in line-break removal function ('J' command). If the newline we find is the last character in the file, we don't delete it, because of Unix convention that text files always end with newlines.

|
fix minor bug when deleting around (with motion like da( or da< or da) or da>). The bug was that, if the last character we delete with the highest index is also the last character at the end of this line, we deleted the range properly but placed the cursor at a linebreak. In this case, the cursor is meant to be a single character before the line break, and after this commit, we have this desired behaviour.

|
in normal mode, when we receive an event which we don't want to handle (like enter), we clear the app's mode and command history instead of simply returning the same app unmodified. This fixes a bug: say we pres 'f' to go to a character and then press enter. Before this commit, pressing a character after that 'enter' will go to that character. This is contrary to Vim, which resets the command history on an invalid command, and now we reset the command history too.
