test_bitmap_printlist() prints the input string which contains
a new line character. Instead of stripping it, escape that kind
of characters, so developer will see the actual input string
that has been used. Without this change the new line splits
the string to two, and the first one is not guaranteed to be
followed by the first part immediatelly.

Grammar nit:

"that kind of characters" -> "those kinds of characters" or "that kind
of character" or "such characters" or ...

immediately

And the second "first" should be "second"??

"the second part is not guaranteed to immediately follow the first" is
clearer (and hopefully what you mean), IMHO.

And "Excape" -> "Escape" - didn't notice until my reply was sending.
