@BurdetteLamar thanks for this work.

I evaluated the changes and found some of the documented behaviour was not aligned with the implementation. Do you mind reviewing my documentation changes? I also added tests (which test what the documentation asserts is true).

FYI, it looks like the behaviour of pretty_inspect changed?

> ruby -Ilib -rcgi -rpp -e "cgi = CGI.new; puts cgi.pretty_inspect"
(offline mode: enter name=value pairs on standard input)
#<CGI:0x00000001220235c8
 @accept_charset=#<Encoding:UTF-8>,
 @accept_charset_error_block=nil,
 @cookies={},
 @max_multipart_length=134217728,
 @multipart=false,
 @options={accept_charset: #<Encoding:UTF-8>, max_multipart_length: 134217728},
 @output_cookies=nil,
 @output_hidden=nil,
 @params={}>

Previously:

> ruby -rcgi -rpp -e "cgi = CGI.new; puts cgi.pretty_inspect"
(offline mode: enter name=value pairs on standard input)
#<CGI:0x0000000100e255a8
 @accept_charset="UTF-8",
 @accept_charset_error_block=nil,
 @cookies={},
 @max_multipart_length=134217728,
 @multipart=false,
 @options={accept_charset: "UTF-8", max_multipart_length: 134217728},
 @output_cookies=nil,
 @output_hidden=nil,
 @params={}>

With some minor changes. LGTM. Thanks.

Thanks, @ioquatix. I'm good with this change. Is the difference b/c I'm using an out-of-date CGI (0.5.-0, in Ruby version 3.4.5)?

@ioquatix, also, I don't like to merge my own work, so when you're satisfied, please feel free to merge.
