nimsuggest: Incorrect highlighting when `*` or `{` is met

[alaviss]

Example:

type
  TypeA = int
  TypeB* = int
  TypeC {.unchecked.} = array[1, int]

nimsuggest highlight output:

highlight	skType	2	2	5 --> Highlight "TypeA" as skType (As expected)
highlight	skType	3	7	5 --> Highlight "* = i" as skType (Totally wrong)
highlight	skType	4	8	5 --> Highlight "{.unc" as skType (Also wrong)
highlight	skType	2	10	3
highlight	skType	3	11	3
highlight	skType	4	24	5
highlight	skType	4	33	3
highlight	skType	2	10	3
highlight	skType	3	11	3
highlight	skType	4	33	3
