  22This is a trivial merge sample text.
  23Branch A is expected to upcase this word, here.
  24There are some filler lines to avoid diff context
  25conflicts here,
  26like this one,
  27and this one,
  28and this one is yet another one of them.
  29At the very end, here comes another line, that is
  30the word, expected to be upcased by Branch B.
  31This concludes the trivial merge sample file.
