ansi color code templates fail to bind symbols

[bluenote10]

The code

import terminal, colors
let code = ansiForegroundColorCode(colAliceBlue)

errors with

../home/fabian/bin/nim-repo/lib/pure/terminal.nim(639, 14) template/generic instantiation from here
../home/fabian/bin/nim-repo/lib/pure/strformat.nim(315, 39) Error: undeclared identifier: 'fgPrefix'

Looking at the source shows that it is probably a consequence of using stformat in a template.
