 The command takes various subcommands, and different options depending
 on the subcommand:

  git bisect good <rev>
  git bisect reset [<branch>]

+Cutting down bisection by giving more parameters to bisect start

 You can further cut down the number of trials if you know what part of
 the tree is involved in the problem you are tracking down, by giving
 paths parameters when you say `bisect start`, like this:
 
 ------------
-$ git bisect start arch/i386 include/asm-i386
+$ git bisect start -- arch/i386 include/asm-i386
+------------
+
+If you know beforehand more than one good commits, you can narrow the
+bisect space down without doing the whole tree checkout every time you
+give good commits. You give the bad revision immediately after `start`
+and then you give all the good revisions you have:
+
+------------
+$ git bisect start v2.6.20-rc6 v2.6.20-rc4 v2.6.20-rc1 --
+                   # v2.6.20-rc6 is bad
+                   # v2.6.20-rc4 and v2.6.20-rc1 are good
 ------------
