Merge branch 'br/blame-ignore'
"git blame" learned to "ignore" commits in the history, whose effects (as well as their presence) get ignored. * br/blame-ignore: t8014: remove unnecessary braces blame: drop some unused function parameters blame: add a test to cover blame_coalesce() blame: use the fingerprint heuristic to match ignored lines blame: add a fingerprint heuristic to match ignored lines blame: optionally track line fingerprints during fill_blame_origin() blame: add config options for the output of ignored or unblamable lines blame: add the ability to ignore commits and their changes blame: use a helper function in blame_chunk() Move oidset_parse_file() to oidset.c fsck: rename and touch up init_skiplist()

--ignore-rev <rev>::
|
||||
Ignore changes made by the revision when assigning blame, as if the
|
||||
change never happened. Lines that were changed or added by an ignored
|
||||
commit will be blamed on the previous commit that changed that line or
|
||||
nearby lines. This option may be specified multiple times to ignore
|
||||
more than one revision. If the `blame.markIgnoredLines` config option
|
||||
is set, then lines that were changed by an ignored commit and attributed to
|
||||
another commit will be marked with a `?` in the blame output. If the
|
||||
`blame.markUnblamableLines` config option is set, then those lines touched
|
||||
by an ignored commit that we could not attribute to another revision are
|
||||
marked with a '*'.
|
||||
|
||||
--ignore-revs-file <file>::
|
||||
Ignore revisions listed in `file`, which must be in the same format as an
|
||||
`fsck.skipList`. This option may be repeated, and these files will be
|
||||
processed after any files specified with the `blame.ignoreRevsFile` config
|

option. An empty file name, `""`, will clear the list of revs from
|

previously processed files.

blame.ignoreRevsFile::
|

Ignore revisions listed in the file, one unabbreviated object name per

`#` are ignored. This option may be repeated multiple times. Empty
