Can't escape backticks using emit pragma

[gradha]

The following example shows backticks are always replaced in the emit pragma:

const code = """
  char s1[] = "Back`tick";
  char s2[] = "Back\\`tick";

  printf("s1: '%s'\n", s1);
  printf("s2: '%s'\n", s2);
  s2[4] = 0x60;
  printf("m2: '%s'\n", s2);
  """

proc emitTest() =
  {.emit:code.}
  echo "Finished"

when isMainModule: emitTest()

The output of this test is:

s1: 'Backtick'
s2: 'Back\tick'
m2: 'Back`tick'
Finished

Backticks are used to replace nimrod variables in the emmited code, but sometimes it would be useful to be able to emit backticks themselves for string literals. Or maybe leave them as they are if no variable is found for replacement.

I will implement it as follows: Two backticks within an emit produce a single backtick.
