[wplug] escaping in sed

[Bob Schmertz]

I'm not sure you've got exactly the right part of the info page, but 
what you're trying to say, I guess, is that Russ can pick another 
character, such as comma, instead of the slash, so the substitution 
expression would look like

s,NEEDLE,NEWNEEDLE,

To make this work, just use it.  Sed recognizes the first character 
after the 's' as the delimiter character to be used throughout the 
expression.

But using backslashes for the escape should work ('s/GNU\/Linux/Linux/' 
-- sorry, I couldn't think of anything else >:-)), as long as everything 
is also in single quotes to protect it from the shell.
