In the olden days,
log --author=me --committer=him --grep=this --grep=that
used to be turned into:
(OR (HEADER-AUTHOR me)
(HEADER-COMMITTER him)
(PATTERN this)
(PATTERN that))
showing my patches that do not have any "this" nor "that", which was
totally useless.
80235ba ("log --author=me --grep=it" should find intersection, not union,
2010-01-17) improved it greatly to turn the same into:
(ALL-MATCH
(HEADER-AUTHOR me)
(HEADER-COMMITTER him)
(OR (PATTERN this) (PATTERN that)))
That is, "show only patches by me and committed by him, that have either
this or that", which is a lot more natural thing to ask.
We however need to be a bit more clever when the user asks more than one
"author" (or "committer"); because a commit has only one author (and one
committer), they ought to be interpreted as asking for union to be useful.
The current implementation simply added another author/committer pattern
at the same top-level for ALL-MATCH to insist on matching all, finding
nothing.
Turn
log --author=me --author=her \
--committer=him --committer=you \
--grep=this --grep=that
into
(ALL-MATCH
(OR (HEADER-AUTHOR me) (HEADER-AUTHOR her))
(OR (HEADER-COMMITTER him) (HEADER-COMMITTER you))
(OR (PATTERN this) (PATTERN that)))
instead.
