[ruby-talk:02228] Misleading IO error message

I got an error message of the following form:

    ./oops.rb:9005:in `open': No such file or directory - /w/x/y/z
(Errno::ENOENT)

But there was such a directory!

What prevented me from finding the retrospectively obvious error in a few
seconds rather than a few minutes was the fact that the newline had been
stripped from the path name that was displayed in the error message. It was
very deceptive at first. (I did some further experimentation and found that
if you have a space character at the end of your path, it is not stripped
in the error message, but you could easily overlook what at first just
looks like normal formatting.)

For this sort of error message, would it be possible to print the actual
string with quotes around it?

    ./oops.rb:15:in `open': No such file or directory - `/w/x/y/z
    ' (Errno::ENOENT)
