help: remove a few commands from `hg` (no args) command list

According to `hg help -e evolve`, the following commands come from the evolve
extension:

amend
evolve
fold
metaedit
next
obslog
pdiff
previous
prune
pstatus
split
touch
uncommit

If one runs `hg` without arguments, commands that are prefixed with a ^
character are shown.  From the previous list, this includes:

evolve
fold
metaedit
next
previous
prune
split
touch
uncommit

It feels several of these commands are not "basic commands" that someone who
has never used hg before might care about.  They probably also do not come
close to passing the "toothbrush test": things that users are likely to use
every day.  This commit removes these items from the list: metaedit, touch,
uncommit

This means the following are kept:

evolve
fold
next
previous
prune
split

Basic case, split a head
  $ hg init testsplit
  $ cd testsplit

  $ echo "change to a" >> _a

To create commits with the number of split
  $ echo 0 > num
  $ cat > editor.sh << '__EOF__'

  > NUM=`expr "$NUM" + 1`
  > echo "$NUM" > num
  > echo "split$NUM" > "$1"
