py3: fix manifestdict.fastdelta() to be compatible with memoryview

This doesn't look nice, but a straightforward way to support Python 3.
bytes(m[start:end]) is needed because a memoryview doesn't support ordering
operations. On Python 2, m[start:end] returns a bytes object even if m is
a buffer, so calling bytes() should involve no additional copy.

I'm tired of trying cleaner alternatives, including:

 a. extend memoryview to be compatible with buffer type
    => memoryview is not an acceptable base type
 b. wrap memoryview by buffer-like class
    => zlib complains it isn't bytes-like

Some Mercurial commands produce a lot of output, and Mercurial will
attempt to use a pager to make those commands more pleasant.

To set the pager that should be used, set the application variable::

  [pager]
  pager = less -FRX

If no pager is set, the pager extensions uses the environment variable
$PAGER. If neither pager.pager, nor $PAGER is set, a default pager
will be used, typically `more`.

You can disable the pager for certain commands by adding them to the
pager.ignore list::

  [pager]
  ignore = version, help, update

To ignore global commands like :hg:`version` or :hg:`help`, you have
to specify them in your user configuration file.

To control whether the pager is used at all for an individual command,
you can use --pager=<value>::

  - use as needed: `auto`.
  - require the pager: `yes` or `on`.
  - suppress the pager: `no` or `off` (any unrecognized value
  will also work).

To globally turn off all attempts to use a pager, set::

  [pager]
  enable = false

which will prevent the pager from running.
