hush: Fix quoting ...

This patch removes adding of an additional \ when doing

I checked in latest busybox hush and this code is still present there,
but it behaves correctly in busybox due to some other code pathes I
didn't investigate.
If this change has any unwanted side effects feel free to flame on me
