prev: prompt user to choose parent in case of multiple parents
This patch adds functionality to `hg prev` to prompt user to choose one parent
to update when multiple parents exist.
Surprisingly there were no tests for this case before this patch, I added one
with this patch.
#require test-repo
$ checkcm() {
> if ! (which check-manifest > /dev/null); then

$ checkcm

Run check manifest:
$ cd $TESTDIR/..
$ check-manifest
