[PATCHv3 00/11] rev-list/log: document logic with several limiting options

In v3 I've rebased my tests on top of Junio's commits which change --all-match handling and provide a better documentation. Accordingly, 6/6 from v2 is dropped and 5/5 adjusted (expect_failure -> expect_success).

I'm sending out Junio's commits as in pu along with 3 intermixed fixups which you may squash in freely. (I've only marked the more obvious one as fixup!.) The last 5 are my rebased tests as described above.

[This approach seemed to be more convenient; hopefully for everyone ;)]

Junio C Hamano (3):
  grep: teach --debug option to dump the parse tree
  log --grep/--author: honor --all-match honored for multiple --grep
    patterns
  log: document use of multiple commit limiting options

Michael J Gruber (8):
  log: name --debug-grep option like in the commit message
  grep: show --debug output only once
  fixup! log: document use of multiple commit limiting options
  t7810-grep: bring log --grep tests in common form
  t7810-grep: test multiple --grep with and without --all-match
  t7810-grep: test multiple --author with --all-match
  t7810-grep: test interaction of multiple --grep and --author options
  t7810-grep: test --all-match with multiple --grep and --author
    options
