Dreamchecker false positive "if condition is always false" with embedded strings

[DamianX]

The original piece of code that triggered this was:

if (!"[A.icon]") // Shitty workaround for a BYOND issue.
	var/icon/temp = I
	I = icon()
	I.Insert(temp, dir = SOUTH)

The bug can be demonstrated with:

world/New()
	..()
	something("lol")
	something()
/proc/something(stuff)
	if(!"[stuff]")
		world.log << 1
	else
		world.log << 2

which outputs:

2
1

with dreamchecker complaining:
