On an EBCDIC machine, be willing to translate mod_autoindex-
generated output.  Otherwise, it doesn't look too cool.

XXX This isn't a perfect fix because this doesn't trigger us
to convert from the charset of the source code to ASCII.  The
general solution seems to be to allow a generator to set an
indicator in the r specifying that the body is coded in the
implementation character set (i.e., the charset of the source
code).  This would get several different types of documents
translated properly: mod_autoindex output, mod_status output,
mod_info output, hard-coded error documents, etc.
