aliases: provide more flexible ways to work with shell alias arguments

This patch changes the functionality of shell aliases to add more powerful
options for working with shell alias arguments.

First: the alias name + arguments to a shell alias are set as an HG_ARGS
environment variable, delimited by spaces. This matches the behavior of hooks.

Second: any occurrences of "$@" (without quotes) are replaced with the
arguments, separated by spaces. This happens *before* the alias gets to the shell.

Third: any positive numeric variables ("$1", "$2", etc) are replaced with the
appropriate argument, indexed from 1. "$0" is replaced with the name of the
alias. Any "extra" numeric variables are replaced with an empty string.  This
happens *before* the alias gets to the shell.

These changes allow for more flexible shell aliases:

    [alias]
    echo = !echo $@
    count = !hg log -r "$@" --template='.' | wc -c | sed -e 's/ //g'
    qqueuemv = !mv "`hg root`/.hg/patches-$1" "`hg root`/.hg/patches-$2"

In action:

    $ hg echo foo
    foo

    $ hg count 'branch(default)'
    901

    $ hg count 'branch(stable) and keyword(fixes)'
    102

    $ hg qqueuemv myfeature somefeature

paragraphs formatted to fit within 60 characters:
----------------------------------------------------------------------
This is some text in the first paragraph.

  A small indented paragraph. It is followed by some lines
  containing random whitespace.

The third and final paragraph.

paragraphs formatted to fit within 30 characters:
----------------------------------------------------------------------

paragraph.

  A small indented paragraph.
  It is followed by some lines
  containing random
  whitespace.

The third and final paragraph.

definitions formatted to fit within 60 characters:
----------------------------------------------------------------------
A Term
  Definition. The indented lines make up the definition.

Another Term
    Another definition. The final line in the definition
    determines the indentation, so this will be indented
    with four spaces.

  A Nested/Indented Term
    Definition.

    spaces.

literals formatted to fit within 60 characters:
----------------------------------------------------------------------
The fully minimized form is the most convenient form:

  Hello
    literal
      world

In the partially minimized form a paragraph simply ends with
space-double-colon.

  ////////////////////////////////////////
  long un-wrapped line in a literal block
  \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

  This literal block is started with '::',
    the so-called expanded form. The paragraph
      with '::' disappears in the final output.

lists formatted to fit within 60 characters:
----------------------------------------------------------------------
- This is the first list item.

  Second paragraph in the first list item.

- List items need not be separated by a blank line.
- And will be rendered without one in any case.

We can have indented lists:

  - This is an indented list item
  - Another indented list item:

      - A literal block in the middle
            of an indented list.

      (The above is not a list item since we are in the literal block.)

  Literal block with no indentation (apart from
  the two spaces added to all literal blocks).

1. This is an enumerated list (first item).
2. Continuing with the second item.
(1) foo
(2) bar
1) Another
2) List

Line blocks are also a form of list:

This is the first line. The line continues here.
This is the second line.

options formatted to fit within 60 characters:
----------------------------------------------------------------------
There is support for simple option lists, but only with long
options:

--all      Output all.
--both     Output both (this description is quite long).
--long     Output all day long.
--par      This option has two paragraphs in its
           description. This is the first.

           This is the second.  Blank lines may be omitted
           between options (as above) or left in (as here).

The next paragraph looks like an option list, but lacks the
two-space marker after the option. It is treated as a normal
paragraph:

--foo bar baz
