The fix for issue #2894 added a binding for \cV. Which prompted the people testing it to notice they had to press \cV twice for the bound function to run. The reason is that the tty driver (kernel, not fish) binds \cV to the "lnext" function. Fish currently undefs stop (\cS) and start (\cQ) so that they can be used in the emacs bindings. Fish should undef all the tty special characters.

It should probably just put the driver in raw mode in which case it wouldn't need to undef any of the special chars. Whether that is a good idea will require looking at the current code to gauge how risky that would be.
