Indenting not working correctly in vectors starting with fn-like symbols

[bpringe]

If I have the below code and press enter with my cursor where noted with | in the first example, it then ends up where noted in the second.

Starting:

(let [context {:a 1
               :b [{:c 2}]}|])

When I press enter:

(let [context {:a 1
               :b [{:c 2}]}
       |])

What I expect after pressing enter:

(let [context {:a 1
               :b [{:c 2}]}
      |])

Oh, wow, this is weird:

(let [context|])

enter

(let [context
       |])

But:

(let [contexs|])

enter

(let [contexs
      |])

So, I think I know what is going on now. context has default indents [[:inner 0]]

If we test that theory with some more default indentations:

;; `[[:inner 0]]`
[fn|]

;; `[[:block 0]]`
[do|]

;; `[[:block 1]]`
[let|]

enter in all the forms

;; `[[:inner 0]]`
[fn
  |]

;; `[[:block 0]]`
[do
  |]

;; `[[:block 1]]`
[let
 |]

So, the bug then is that our indenter doesn't check for the type of list it indents. Amazing.
