One little wrinkle that might complicate moving the case_sensitive
attribute into server blocks in 3.2 config files is the fact that this
attribute also affects the handling of other global attributes.  For
instance, htdig makes regular expression patterns out of limit_urls_to,
exclude_urls, and others, and compiles these patterns before starting to
dig.  When it compiles them, it uses the "ignore case" option if the
case_sensitive attribute is false.  Changing case_sensitive in a server
block will have no effect on patterns already compiled, so the global
setting will still matter.  You don't want to start recompiling all your
patterns on a document by document basis either, though!
