[PATCH 6/8] docs: use <tree> instead of <tree-ish>

[Mark Lodato <lodatom@gmail.com>]

No git command, besides commit-tree, accepts only a tree and not
a tree-ish, so let us remove the latter term from common usage in the
documentation in order to reduce the amount of jargon.

The term "tree-ish" was left in the following situations:
 - all comments in the code
 - situations where "tree-ish" is being contrasted to "tree"
 - error messages, to prevent porcelains from changing
 - tests
 - the glossary
