Also, it's what Linus has asked people to do.

More to the point, this is a matter of courtesy.  Sure, you can save
yourself 10 seconds of copy & paste, at the cost of making dozens of
readers expend a similar amount of time to learn what you're talking
about.  If you expect people to read what you write, it's good form not 
to force them to go out of their way to understand you.
