insert repeat gets confused by `delete`

[jacekkopecky]

in insert mode, delete will remove the character following the cursor, but . doesn't replay it correctly. Demonstration of the problem:

1. have 1234 in the editor and the cursor is on 2
2. type iabc<delete><esc> – you should have 1abc34 in the editor and the cursor on c
3. move cursor on the 1
4. type . – you should have abcabc34 in the text editor, with cursor on the first c (the original 1 would get eaten by the repeated delete)

But what you actually get is ab1abc34 with cursor on the first b.

The problem is in TransactionBundler in input.coffee which treats the delete as a backspace.

Thanks for fixing this.
