Rework installation instructions again

Dept. of second thoughts: the new verbiage added in commit aaec237b1a2f
is targeted at the wrong audience.  Remove the bits about git and talk
about how to get tarballs only.  People looking for the git repo can
look in the appendix.  That'll need to be expanded, but this commit
doesn't do that.

In passing, fix a couple of typos that snuck in with the previous
commit.
