You should be able to do 'emacs -Q filename.rb' however.

I see you using the old idiom ${1+"$@"}.  That is fine.  That will
work everywhere.  But unless you are working on Solaris then that
idiom can be shorted to simply "$@" without checking $1 first.  All
modern shells treat "$@" correctly now and it is required by POSIX.

You have been focusing on trying to get the "open" to work.  But you
could just for the experiment try emacs in a terminal window and get
the test done.

  emacs -nw -Q

Just ignore the who "open" problem for the moment and just test
whether -Q causes your curly brace problem to go away.  Because if
it does then you now the problem is in your emacs customization in
your ~/.emacs or wherever you are locating it.
