[PATCH v2 3/7] use 'treeish' instead of 'tree-ish'

[Richard Hansen <rhansen@bbn.com>]

Replace all instances of 'tree-ish' with 'treeish':
  * to standardize on a single spelling (the documentation contained a
    mix of 'treeish' and 'tree-ish')
  * to be consistent with variable names (hyphens are not usually
    allowed in variable names)
  * to be consistent with 'committish'
  * some search engines don't handle hyphens gracefully
