I'm with you that we don't want to be in the business of documenting every little thing they'd need to know, like python or apache. IMO, git is a slightly more gray area since it's not really similar to SVN/CVS but there is a mentality of "Ah, it's version control, I know this". The barrier of entry to git is, again IMO, a lot higher than other VCSes so a few examples of just enough knowledge wouldn't hurt.

I also don't feel terribly strongly about including an example here, so don't take this reply to be me strongly pushing for it. I know that personally, when I create a new repo in github in my account, I appreciate that they give me a list of example commands to use to init it.
