- Add some links. - Remove the space in "character set" in the syntax of ProxyFtpDirCharset to avoid confusion (it is 1 parameter only) - Use the correct syntax for the "default" values, so that they are parsed and correctly displayed in 'quickreference' - Remove extra  when directive's parameter are required
- correct the default password: apache-proxy@ instead of apache_proxy@. This was silently changed in r88745, 17 years ago!
(r1838313 in trunk + some style to synch 2.4.x and trunk)
