help: apply bulk fixes for indentation and literal blocking issues

There are some paragraphs, which aren't rendered in online help as
expected because of indentation and literal blocking issues.

- hgext/rebase.py

  - paragraph before example code ends with ":", which treats
    subsequent indented paragraphs as normal block

    => replace ":" with "::" to treat subsequent paragraphs as literal block

- help/pager.txt

  - paragraph before a list of --pager option values ends with "::",
    which treats subsequent indented paragraphs as literal block

    => replace "::" with ":" to treat subsequent paragraphs as normal block

  - the second line of explanation for no/off --pager option value is
    indented incorrectly (this also causes failure of "make" in doc)

    => indent correctly

- help/revisions.txt

  - explanation following example code of "[revsetalias]" section
    isn't suitable for literal block

    => un-indent explanation paragraph to treat it as normal block

  - indentation of "For example" before example of tag() revset
    predicate matching is meaningless

  - descriptive text for tag() revset predicate matching isn't
    suitable for literal block

    => un-indent concatenated two paragraphs to treat them as normal block

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, Mercurial uses the environment variable
$PAGER. If neither pager.pager, nor $PAGER is set, a default pager
will be used, typically `less` on Unix and `more` on Windows.

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.
