Merge branch 'jc/doc-log-rev-list-options'

"git log --help" used to show rev-list options that are irrelevant
to the "log" command.

        objects in deltified form based on objects contained in these
        excluded commits to reduce network traffic.
  
 +--objects-edge-aggressive::
 +      Similar to `--objects-edge`, but it tries harder to find excluded
 +      commits at the cost of increased time.  This is used instead of
 +      `--objects-edge` to build ``thin'' packs for shallow repositories.
 +
+ --indexed-objects::
+       Pretend as if all trees and blobs used by the index are listed
+       on the command line.  Note that you probably want to use
+       `--objects`, too.
+ 
  --unpacked::
        Only useful with `--objects`; print the object IDs that are not
        in packs.
