terminal.nim says i don't have a true color term (but it's wrong)

[jrfondren]

It's set in several places of 
[enableTrueColors](https://github.com/nim-lang/Nim/blob/version-1-4/lib/pure/terminal.nim#L865).
 So a good start, since you're not already looking at that proc, is to call it 
and see if that fixes your problem.
