The backslash has to do with the double quotes (as opposed to using
single quote).

I wanted to make it so you could avoid the escape. If it's not an issue
(I have a damn hard time finding an example of a legacy implementation
that depends on it... I suspect there are none), then making the escape
non-transparent is a better method.
This was sort of a preemptive strike against people who would bitch on
principle rather than fact... we know who we are... 8-).
