Optimize the size more

[Steve Kemp]

We overhauled the output of strings when we added support for wrapping output:

• When we see an 0x0d
  • We print 0x0a and 0x0d
  • (Except on Spectrum where we just print 0x0d)
• When we see an 0x0a
  • We ignore it.

That means we could save a lot of bytes by just deleting the 0x0a from our string collection.
