An additional note: One of the following is needed:

* Detect the end of line (this may be tricky) and split the coloring
  into 2 parts (each one with space + backspace + escape sequence)
  at this point. If this detection is incorrect, then the background
  problem would still be visible, but with no major drawbacks.

* Split the coloring so that each matching character gets a space +
  backspace + escape sequence. I think that this is acceptable since
  this trick should be used only when the output is a tty (i.e. it
  is not redirected to a file / not piped to a pager or something
  else).
