Subject: [PATCH] Add bracket indentation semantics to (* *)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Background: ionide/ionide-fsgrammar#209

This comes from a comment regarding a pull request that I made on the
ionide-fsgrammar repository, which removes the `(* *)` bracket pair
from the "brackets" field of language-configuration.json. One issue
with doing this is that we lose the bracket-like indentation that
VSCode provides by default for all bracket pairs.

In other words, when I hit Enter in the following configuration,
cursor location represented by the white block:

    (*█*)

It should indent the cursor and then put the `*)` on the next line
with the same indentation level as the `(*` as follows:

    (*
        █
    *)

---

When I hit Enter with an unaccompanied `(*`:

    (*█

It should simply indent as follows:

    (*
        █

---

Lastly, an unaccompanied `*)` should outdent. That is,

        *)█

should become

    *)█
