What does SEARCH_SUGGEST now entail?  Is that bucket deprecated?  Please
document within this proto file.

Meaning of SEARCH_SUGGEST doesn't change. Although I can rename it to
SEARCH_SUGGEST_QUERY if you want. These suggestion types are newly being added
to Chrome omnibox.

Don't rename SEARCH_SUGGEST, but do update the comments here and in
autocomplete_match_type.h to add "...that doesn't fall into one of the more
specific suggestion categories below" to its description.

+1 to this suggestion.

And, when this is resolved, please make sure the internal google file is
identical (i.e., same comment, formatting, etc.)

And also please try to keep the autocomplete_match_type comments in sync with
this as well.  (formatting not important, but content should be equivalent)

[Anuj, 2013/12/10 23:08:09]

Done.

[Anuj, 2013/12/10 23:08:09]

Done.
