Create a repo with some stuff in it:
$ hg init a
$ cd a
$ echo a > a
$ echo a > d
$ echo a > e
$ hg ci -qAm0
$ echo b > a
$ hg ci -m1 -u bar
$ hg mv a b
$ hg ci -m2
$ hg cp b c
$ hg ci -m3 -u baz
$ echo b > d
$ echo f > e
$ hg ci -m4
$ hg up -q 3
$ echo b > e
$ hg branch -q stable
$ hg ci -m5
$ hg merge -q default --tool internal:local
$ hg branch -q default
$ hg ci -m6
Need to specify a rev:
$ hg graft
abort: no revisions specified
[255]
Can't graft ancestor:
$ hg graft 1 2
skipping ancestor revision 1
skipping ancestor revision 2
[255]
Can't graft with dirty wd:
$ hg up -q 0
$ echo foo > a
$ hg graft 1
abort: outstanding uncommitted changes
[255]
$ hg revert a
Graft a rename:
$ hg graft 2 -u foo
grafting revision 2
merging a and b to b
$ hg export tip --git
# HG changeset patch
# User foo
