 Use cachmgr.CGI logic for interpreting Squid manager reports
 sent in text/plain format:

 - any given line can be part of three constructions:
   table header, table data, or pre-formatted text

 - lines beginning with multiple whitespace are equivalent to a tab (\t).

 - lines containing a tab (\t) are table rows in TSV format.
