The name `truncate-lines' does not give any hint that it controls word wrapping too. Do you care about this? If so, how about this: make truncate-lines an obsolete alias for `line-wrap-method', which accepts the values `edge-wrap', `word-wrap', and `truncate', with t equivalent to `truncate' and nil equivalent to `edge-wrap'. >> I have also changed truncate-partial-width-windows to accept integer >> values specifying a window width below which to truncate lines, and >> changed the default to 30. > > Since the Emacs-22 default was t, I think a safer new default (other > than t) would be something around 70-80, so it behaves as before for > 80 column frames. For anyone using the word-wrap feature, that could be annoying. With word wrapping, buffers with long lines can be comfortably read in 50-column windows, but if truncate-partial-width-windows is 70-80, they'll be truncated rather than wrapped.
