help: improve merge-tools topic, describe --tool and clarify details

This doesn't make it simpler, but it makes it more correct.

With help from erikz, mg and abuehl.

Tests whether or not hgwebdir properly handles various symlink topologies.

  $ "$TESTDIR/hghave" symlink || exit 80
  $ hg init a
  $ echo a > a/a
  $ hg --cwd a ci -Ama -d'1 0'
  adding a
  $ mkdir webdir
  $ cd webdir
  $ hg init b
  $ echo b > b/b
  $ hg --cwd b ci -Amb -d'2 0'
  adding b
  $ hg init c
  $ echo c > c/c
  $ hg --cwd c ci -Amc -d'3 0'
  adding c
  $ ln -s ../a al
  $ ln -s ../webdir circle
  $ root=`pwd`
  $ cd ..
  $ cat > collections.conf <<EOF
