Subject: Bug #172496 - Add a PORTAGE_COMPRESS_EXCLUDE_SUFFIXES config variable
 which is used to filter ecompress arguments. This allows the user to control
 compression of files installed dodoc, excluding files with specific suffix
 patterns. The current default value includes all of the suffixes that are
 recognized by dohtml, as well as pdf.
