I don't know. But changing " into ' is OK too. The reason is: it is Ruby
that removes the \ when evaluation (load "C:\home\test.rb") whereas it
does not for (load 'C:\home\test.rb').

Matz, I think you are the maintainer of inf-ruby.ev, you may want to modify
it so that it works better on Windows (and also handle well strangely named
files with \ in their name...)

Yours,
