formatting: drop `grey`, our custom black version
Now that the official black has all we want, we can drop this.
Test for the heuristic copytracing algorithm
============================================
$ cat >> $TESTTMP/copytrace.sh << '__EOF__'
> initclient() {
> cat >> $1/.hg/hgrc <<EOF
> [experimental]
> copytrace = heuristics
> copytrace.sourcecommitlimit = -1
> EOF
> }
> __EOF__
$ . "$TESTTMP/copytrace.sh"
$ cat >> $HGRCPATH << EOF
> [extensions]
> rebase=
> [alias]
> l = log -G -T 'rev: {rev}\ndesc: {desc}\n'
> pl = log -G -T 'rev: {rev}, phase: {phase}\ndesc: {desc}\n'
> EOF
NOTE: calling initclient() set copytrace.sourcecommitlimit=-1 as we want to
prevent the full copytrace algorithm to run and test the heuristic algorithm
without complexing the test cases with public and draft commits.
