hgrc.5: reformatted to avoid big chunks of monospaced text

The man page used to have lines longer than 80 characters, even though
all lines in the hgrc.5.txt file were wrapped nicely. The problem
turned out to be that the indented paragraphs started literal blocks
instead of normal paragraphs. The literal blocks were of course not
wrapped when displayed by man.

In short, the asciidoc rules require lists to be formatted like this:

foo::
  Some description of foo.
+
Another paragraph in the description of foo. It *must* start flush
left and the plus is necessary to indicate that this is a list item
continuation.

Lists with nested lists can be formatted correctly using something
called "open blocks". These blocks are used to group the list items
and are marked by a line above and below with two dashes. See the
asciidoc user guide for the gory details...

   Aliases allow you to define your own commands in terms of other
   commands (or aliases), optionally including arguments.

+--
 Alias definitions consist of lines of the form:
-+
+
     <alias> = <command> [<argument]...
-+
+
 For example, this definition:
-+
+
     latest = log --limit 5
-+

 creates a new command `latest` that shows only the five most recent
 changesets. You can define subsequent aliases using earlier ones:
-+
+
     stable5 = latest -b stable
-+

 *Note*: It is possible to create aliases with the same names as
 existing commands, which will then override the original definitions.
 This is almost always a bad idea!

-  Python hooks are run within the Mercurial process. Each hook is
-  called with at least three keyword arguments: a ui object (keyword
-  "ui"), a repository object (keyword "repo"), and a "hooktype"
-  keyword that tells what kind of hook is used. Arguments listed as
-  environment variables above are passed as keyword arguments, with no
-  "HG_" prefix, and names in lower case.
