git-codereview: limit reviewer search to last 1000 commits

The vast majority of reviewers are consistently active,
so limiting the search to the last 1000 commits won't
lose many folks. And not loading every commit for a git mail
helps with speed and avoids thrashing the disk cache,
which is a pain point on my slow, spinning platter.

Before, with a warm cache:

$ time git log --format=format:%B | wc -l
  301515

real	0m0.860s
user	0m0.398s
sys	0m0.164s

After, with a warm cache:

$ time git log --format=format:%B -n 1000 | wc -l
   16765

real	0m0.036s
user	0m0.021s
sys	0m0.021s
