more than 20 commands in everyday.txt

hi,

this might seem to be a bit bikesheding, but i hope it isn't. today i teched git to someone who never used any scm so far. i showed him the "everyday with git" document, as i think it's a great start for newbies. actually i read it once but it was in the past, now i did it again and i think there are some commands listed there which is not something we use "every day". of course it may be only me, that's why i ask. here are the commands i rarely use and are in everyday.txt:

- git-prune and git-repack: usually i use git-gc only. maybe prune and
  repack could be removed from everyday.txt?

- git-show-branch: what about mentioning gitk instead? i think it's much
  more used - compared to git-show-branch

what do you think about this? maybe i'm wrong, but if i'm right, then i would provide a patch to update everyday.txt according to these suggestions.

thanks,
