The reason there are 21 is:
$ grep -c "mainporcelain common" command-list.txt
21
Perhaps if `git help` is going to be some subset of that aimed at
newbies a new command-list.txt category should be introduced as part
of the patch? E.g. "mainporcelain common newbie"?
As a further suggestion for future improvements, perhaps we should
document *all* commands in the future, or at least those in
mainporcelain and make a full summary available through `git help
--full` or something like that.
As far as I can see with this patch the the description for the
commands you removed in the `cmdname_help common_cmds` struct is now
dead code. If that's the case shouldn't they strings be removed from
there?
These are the commands you removed (I think the commit message should
be changed to explicitly mention this):
git-bisect mainporcelain common
git-grep mainporcelain common
git-mv mainporcelain common
git-rebase mainporcelain common
git-rm mainporcelain common
"mv" and "rm" are certainly something a newbie might frequently
used. Why not list it under "Basic commands" along with "add"?
I use "rebase" much more than some of the commands now listed, it's
one of the main distinguishing features of git, so perhaps it should
be under "Branch Commands", if for no other reason than to give users
a peek down the rabbit hole.

Why capitalize "Commands" when it's not at the beginning of a
sentence? 'bzr help' doesn't do this. And For What It's Worth I Find
It Uncomfortable To Read Text Formatted Like That.
