nimsuggest-mode: Invalid face reference: face

[kaushalmodi]

For this simple code where I was experimenting with noSideEffect:

proc sum(x, y:int): int {. noSideEffect .} =
  echo x # causes side effect
  x + y

echo sum(2,3)

and with nimsuggest-mode enabled and flycheck-mode disabled, I get this in the *Messages* buffer:

Invalid face reference: face

each time, I place the point on

proc sum(x, y:int): int {. noSideEffect .} =

• [x] Are you using latest version of nim-mode?
  • Yes
• [x] Are there message related to nim-mode in *Messages* buffer?
  • No. Just that I get Invalid face reference: face each time I put the point on proc sum(x, y:int): int {. noSideEffect .} =.
• [x] Did you read README.md?
  • Yes.
• [x] Is your problem related to nimsuggest-mode? (company-mode, flycheck, or el-doc)
  • Yes, nimsuggest-mode.
  • [x] Did you try nim-mode without nimsugggest-mode? What happened?
    • The issue goes away if I disabled nimsuggest-mode.

I think it has to do with the pragma.. if I remove the pragma from that first line, the invalid face error goes away:

proc sum(x, y:int): int =

I'm not sure this is related to #166, but I could only reproduce on nimscript-mode and I think I fixed #166. Please re-open if this issue is still remaining.
