`(if (form)<Enter>` does not indent the new line

[WalterGR]

Repro:

1. Open a .clj file.
2. Type the following in the file, at the top level, and press Enter/Return.

(if (form)

Expected:

The cursor is indented on the new line by 2 spaces:

(if (form)
  _

Actual:

The cursor is not indented at all:

(if (form)
_

Strangely, if you instead type the following (i.e. form not enclosed in parens) and press Enter/Return:

(if form

then the new line is indented.

I think I can solve with simple solution, by add increaseIndentPattern to settings

'.source.clojure':
  'editor':
    'commentStart': '; '
    'increaseIndentPattern': '\\('

if @50Wliu agreed, I'll make a pull request.

As long as you can ensure that there are no unintended side-effects of that change, feel free to make a PR.
