[PATCH] Add --diff-filter= output restriction to diff-* family.
This is a halfway between debugging aid and a helper to write an ultra-smart merge scripts. The new option takes a string that consists of a list of "status" letters, and limits the diff output to only those classes of changes, with two exceptions: - A broken pair (aka "complete rewrite"), does not match D (deleted) or N (created). Use B to look for them. - The letter "A" in the diff-filter string does not match anything itself, but causes the entire diff that contains selected patches to be output (this behaviour is similar to that of --pickaxe-all for the -S option). For example, $ git-rev-list HEAD | git-diff-tree --stdin -s -v -B -C --diff-filter=BCR shows a list of commits that have complete rewrite, copy, or rename.
