which swaps Enter and semicolon in Insert and Command-line mode. Strange
idea. So you hit the Enter key to insert a semicolon into text, and you
hit the semicolon key to break the line? Weird.

The seven eyes of Ningauble the Wizard floated back to his hood
as he reported to Fafhrd: "I have seen much, yet cannot explain all.
The Gray Mouser is exactly twenty-five feet below the deepest cellar in
the palace of Gilpkerio Kistomerces. Even though twenty-four parts in
twenty-five of him are dead, he is alive.
"Now about Lankhmar. She's been invaded, her walls breached
everywhere and desperate fighting is going on in the streets, by a
fierce host which out-numbers Lankhmar's inhabitants by fifty to one --
and equipped with all modern weapons. Yet you can save the city."
"How?" demanded Fafhrd.
Ningauble shrugged. "You're a hero. You should know."
