Subject: Change all user-visible references to the noun "screen" to use "frame"
X-Git-Tag: 20090517-FFI~5592
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=4babc700e8104b9cccacd1e6614db36e849e0b04;p=mit-scheme.git

Change all user-visible references to the noun "screen" to use "frame"
instead, for consistency with Emacs 19.
