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-backup.hg (glob)
$ hg log -r 23fe4ac6d3f1
abort: unknown revision '23fe4ac6d3f1'!
