Re: [PATCH 1/4] glossary: add 'treeish' as a synonym for 'tree-ish'

Perhaps something like:

-[[def_tree-ish]]tree-ish::
+[[def_tree-ish]]tree-ish (sometimes misspelled treeish)::

would be satisfactory?

If it is a misspelling, I do not think we need to list both.  An
entry "tree-ish" can be found if you were looking for treeish.

If it is not, then "sometimes misspelled" should perhaps is better
"aka".

I do not personally have a very strong preference between the dashed
and dashless forms, but if I really have to pick one over the other,
I would probably go with tree-ish, commit-ish, as these are not real
words.  I do have mild preference of not listing both to keep things
shorter and cleaner.
