Standardize the way M-x commands are written:

dashes inside command names, not spaces; spaces before <Return>.
(Summary): Describe the new behavior of C-l.
(Basic Cursor Control): Don't say that files "ought" to end in newlines.
Try to distinguish scroll bar from fringes.
You can also scroll with a wheel mouse.
(If Emacs Stops Responding): Rename from "When Emacs is hung".
(Inserting And Deleting): Continuation marks appear in the fringe.
Clarify that deletion can be undone.  Mention cut and paste, and the Glossary.
(Files, Mode Line): Update mode-line format.
(Extending The Command Set): Downplay C-z, since using Emacs on a
text-only terminal is less common these days.
(Searching): Incremental searching is no longer atypical.
Downplay flow control issues, remove reference to deleted FAQ node.
(Multiple Windows): Mention frames.
(Multiple Frames): New section.
(Getting More Help): Downplay C-h having a different binding.
Don't say help is "on-line", since the meaning has changed.
(More Features): Replace "on-line".  Use C-h rather than F10 h.
Say a little more about completion.
(Conclusion): Don't mention C-z again here.
