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