It would be great if this got fixed in bash itself, but in the
meantime this workaround will help, thanks :)
I've noted that it creates some artifacts when you resize the terminal
after a command that ends without a newline, though.
Would you mind explaining the code a bit? Eg: why is "(:);" in there,
or why do we need $_prompt_xenl_offset ?
