tests: add test about aborting content-divergence when multiple parents
This patch adds tests for --abort flag of hg evolve command when we are
resolving content-divergence which are on different parents and parent of one of
them is the gca of both of them.
The tests shows that we are doing good and we should advertise the flag during
conflicts.
ensure that all the scenarios in the user guide work as documented
basic repo
$ hg init t
$ cd t
$ touch file1.c file2.c
$ hg -q commit -A -m init
example 1: commit creates a changeset in draft phase
(this is nothing to do with evolve, but it's mentioned in the user guide)
$ echo 'feature Y' >> file1.c
$ hg commit -u alice -d '0 0' -m 'implement feature X'
$ hg phase -r .
1: draft
$ hg identify -in
6e725fd2be6f 1
example 2: unsafe amend with plain vanilla Mercurial: the original
commit is stripped
$ hg commit --amend -u alice -d '1 0' -m 'implement feature Y'
saved backup bundle to $TESTTMP/t/.hg/strip-backup/6e725fd2be6f-42cc74d4-amend.hg (glob)
$ hg log -r 23fe4ac6d3f1
abort: unknown revision '23fe4ac6d3f1'!
[255]
$ hg identify -in
fe0ecd3bd2a4 1
enable evolve for safe history modification
$ cat >> $HGRCPATH <<EOF

> [extensions]
> rebase =

$ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
example 3: safe amend with "hg commit --amend" (figure 2)
$ echo 'tweak feature Y' >> file1.c
$ hg commit --amend -u alice -d '2 0' -m 'implement feature Y'
$ hg shortlog -q -r fe0ecd3bd2a4
abort: hidden revision 'fe0ecd3bd2a4' was rewritten as: 934359450037!
