Format quoted string verb not supported inside Terraform configuration function definition

[bflad]

Description

When using terrafmt diff -f with the following configuration snippet:

	return fmt.Sprintf(`
data "aws_caller_identity" "current" {}

resource "aws_signer_signing_profile" "test" {
  platform_id = "AWSLambda-SHA384-ECDSA"
  name        = replace(%[1]q, "-", "_")
}
# ...
`, rName)
}

An error is returned because the string is not quoted properly during format verb handling (note: replace(TFFMTKTBRACKETPERCENT[1]q, \"-\", \"_\")):
