Re: [PATCH] merge-recursive: do not report the resulting tree object name

I like this patch. merge-recursive is very talkative, to the intimidating 
astonishment of unsuspecting users.

This is a smallish example:

        $ git merge jc/merge-base
     1	Trying really trivial in-index merge...
     2	fatal: Merge requires file-level merging
     3	Nope.
     4	Merging HEAD with jc/merge-base
     5	Merging:
     6	b60daf0 Make git-prune-packed a bit more chatty.
     7	5b75a55 Teach "git-merge-base --check-ancestry" about refs.
     8	found 1 common ancestor(s):
     9	1c23d79 Don't die in git-http-fetch when fetching packs.
    10	Auto-merging Makefile
    11	Auto-merging builtin-branch.c
    12	Auto-merging builtin-reflog.c
    13	CONFLICT (content): Merge conflict in builtin-reflog.c
    14	Auto-merging builtin.h
    15	Auto-merging git.c
    16	Removing merge-base.c
    17	Resolved 'builtin-reflog.c' using previous resolution.
    18	Automatic merge failed; fix conflicts and then commit the result.

Among these, I think lines 2..3 are somewhat confusing but I am
used to seeing them and do not mind them too much.

Lines 4..9 do not have any real information that helps the end
user (even though it would be a very good debugging aid for
merge-recursive developers).

Lines 10..16 are useful, but I think we probably should show
them only for outermost merges.

An multi-base example:

        $ git merge 82560983997c961d9deafe0074b787c8484c2e1d
     1	Merging HEAD with 82560983997c961d9deafe0074b787c8484c2e1d

I do not think we need to show 1..15 at all, perhaps without
"export GIT_MERGE_BASE_DEBUG=YesPlease".
