t4034: add tests showing problematic cpp tokenizations

The word regex is too loose and matches long streaks of characters
that should actually be separate tokens.  Add these problematic test
cases. Separate the lines with text that will remain identical in the
pre- and post-image so that the diff algorithm will not lump removals
and additions of consecutive lines together. This makes the expected
output easier to read.
