Interesting.

 - "exec_cmd.h" became unnecessary at b931aa5a (Call builtin ls-tree
   in git-cat-file -p, 2006-05-26).

 - "tag.h" and "tree.h" became unnecessary at 21666f1a (convert
   object type handling from a string to a number, 2007-02-26).

 - "diff.h" was added at e5fba602 (textconv: support for cat_file,
   2010-06-15), together with "userdiff.h".  Was it unnecessary from
   the beginning?

I didn't dig further to find out the answer to the last question,
but a patch to remove these include should explain these in its log
message, I would think.

Thanks.
