Ok, I see now. Many commands are expected to work on the visual representation, so only a few commands that incorrectly treat inserted newlines should be fixed. I see no problem in matching additional newlines in `query-replace' and the regexp search, but I don't see how to distinguish soft newlines inserted by longlines-mode and hard newlines with the `hard' property using the regexp search, i.e. how (re-search-forward "[ \t\n]") could find soft newlines and skip hard newlines? -- Juri Linkov http://www.jurta.org/emacs/
