Little fix and suggestion for the git tutorial

Sorry for not sending a patch, I was following the tutorial and found this, in the section "Using git for collaboration":

 307 With this, you can perform the first operation alone using the
 308 "git fetch" command without merging them with her own branch,
 309 using:

I think that "you" should be replaced with "she".

I have a suggestion also that I don't know how to fix. The text in that section seems to say something like you need to add a "remote" alias to be able to run fetch for retrieving without merging:

...[remote add <alias>]...

 307 With this, you can perform the first operation alone using the
 308 "git fetch" command without merging them with her own branch,
 309 using:

....[fetch <alias>]...

 315 Unlike the longhand form, when Alice fetches from Bob using a
 316 remote repository shorthand set up with `git remote`, what was
 317 fetched is stored in a remote tracking branch, in this case
 318 `bob/master`.  So after this:

I'm not sure, but I think that you could use fetch without the need of an alias. I think that here it is trying to avoid more advanced explanations or longer commands, however I don't know how to say it better, perhaps mentioning that this way it is easier, without omitting that it could be done without a "remote" alias for the repo.

That's all, thank you
