Hi Teng,

Could you spend some time in your commit message explaining what
is wrong about the characters used for bullet points here?

Is it that the indentation isn't enough to show a sublist? I see
that the HTML rendering on git-scm.com [1] does fail to show this
sublist, and I could believe that this change would fix it (but I
am not sure).

That's it. ASCIIDoc doesn't treat an indented dash character as the
beginning of a sub-list. It will treat an indented asterisk as beginning
a sub-list, but only if the rest of the list items begin with a "-".

It might just be worth converting this whole thing to use what ASCIIDoc
would probably consider to be a more standard format, i.e.:

    * A list of packfile names.
    * A sorted list of object IDs.
    * A list of metadata for the ith object ID including:
    ** A value j referring to the jth packfile.
    ** An offset within the jth packfile for the object.
    * If large offsets are required, we use another list of large
      offsets similar to version 2 pack-indexes.

Yeah, Teng's fix works just fine. So I'd be happy to see that picked up
(with or without much additional explanation).

Thanks,
Taylor

That's right.

There are some questions here.
I think the indent is not needed for bulleted list in ASCIIDOC. If we
want to write a nested bulleted list, we could just use asterisks
without any dashes like:

"
* Level 1 list item
** Level 2 list item
*** Level 3 list item
** Level 2 list item
* Level 1 list item
** Level 2 list item
* Level 1 list item
"

And the dashes are suggested only be used as the marker for the first
level because the dash doesn’t work well or a best practice for nested
lists, like (dash is as level 2):

"
* Level 1 list item
- Level 2 list item
* Level 1 list item
"

But, if you are writting a non-nested bulleted lists, use dashes works
too, like:

"
- Level 1 list item
- Level 1 list item
- Level 1 list item
"

I agree with you.

The asterisks are recommanded to use I think, it displays intuitively
when writting ASCIIDOC lists (marker length = nesting level).

I found it because I'm learning about the implements about the
multi-pack-index, reverse-index and multi-pack-bitmap, very nice
feature.

Patch v2 will add more descriptions (Derrick Stolee suggested) in
commit message and will make the replacements from dashes to asterisks.

Finally, thanks Derrick Stolee and Taylor Blau for the relies.
