Recording to registers with custom escape mapping

[auwsmit]

I have this mapping in my vimrc: inoremap <C-G> <Esc> which seems to be causing a bug with incsearch.

So, with that mapping, here's how to reproduce this error:

1. Mark origin point mm
2. Record to a register qq
3. Search for any valid word /foo
4. Enter insert or replace mode in any way, i or c or R, etc
5. Enter any text bar
6. Exit insert mode via <C-g> (or any user-mapped <Esc> equivalent)
7. End recording q
8. Undo all changes u
9. Go back to start `m
10. Play back recording @q

When playing back the recording, it adds the text (_incsearch-hlsearch) while in insert mode, thus breaking the recording. This doesn't happen with regular <Esc> or <C-[>
