Take II of the shell consistancy change. Although I agree that the use
of '.' is easier on the eyes, 'x' does seem more common and old-dog shell programmers kind of expect it. It's also easier to search for in vi :) Some may question why we need to wrap or protect if we are sure that the $var isn't null, but it really doesn't cost that much for the extra insurance and it stops people from having to shift "mental gears" when they run across such statements. Some may question why even bother with a consistant style... I think it's important to write readable code and understandable code and code that others can maintain easily. A consistant style, IMO, helps this effort. It also just plain looks better :) PR: Obtained from: Submitted by: Reviewed by: git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/1.3.x@82676 13f79535-47bb-0310-9956-ffa450edef68
