Make this a pure-ASCII file. This used to have a Latin-1 coding and

contain several string literals using non-ASCII characters.  Because
of the pain of displaying those characters, it's better to use \xXX
escapes for these instead of typing the accented characters.

Apologies if I missed something; it didn't look like there was anything
that depended on this file being encoded in Latin-1 or containing non-ASCII
characters.
