# changes by dscherer@cmu.edu
#   - IOBinding.open() replaces the current window with the opened file,
#     if the current window is both unmodified and unnamed
#   - IOBinding.loadfile() interprets Windows, UNIX, and Macintosh
#     end-of-line conventions, instead of relying on the standard library,
#     which will only understand the local convention.
