Heh, I was going to report that too---I found that in the backport of
readline, but I couldn't decide whose bug it really was.

So what this means is that

a = [[b
]]

has two characters in it, regardless of whether it's typed at the command
line or read from a file.

Is it a good idea to support "\\\n" such that

a = [[b\
]]

has only one character in it?
