(rework) [PATCH 3/4] Accept commit in some places when tree is needed.

(rework) [PATCH 3/4] Accept commit in some places when tree is needed.

[Junio C Hamano]

Updates ls-tree.c to use read_tree_with_tree_or_commit_sha1()
function.  The command can take either tree or commit IDs with
this patch.

Sorry, but the numbering is wrong this should have been [4/5]
not [3/4].  The contents should be fine, though.

Applied and pushed out.

Btw, I edited your subject lines to make them be more specific
to one particular patch.

Thanks.  I have alreay a bugfix and a half X-<.

----------------------------------------------------------------
[PATCH] Fix read-tree-with-tree-or-commit-sha1 function.

Instead of NULL to signal an error, it was returning a garbage.
Also the compiler complains about a type mismatch between signed
and unsigned character array.  Both are my bad.  Sorry.
