Why do the install docs use Apache Alias w/ trailing slash?

http://list.org/mailman-install/node10.html

This reference seems to make a solid argument for not using trailing slashes:

http://httpd.apache.org/docs/misc/FAQ-E.html#set-servername

The 'ScriptAlias' trailing slash may not hurt much of anything (although I plan on being consistent and tell my Apache admins to always eliminate trailing ScriptAlias and Alias slashes as a general rule...for consistency's sake--any problems with this?), but the Alias trailing slash can cause problems as per above...I think.

Am I overlooking something? If so, I'd like to get to the bottom of it so I get my Mailman server working correctly for all user scenarios.
