As noted in CodingGuidelines, error messages should not be capitalized. Fix up a few of these that were copied verbatim from merge-recursive to match our modern style. We'll likewise fix up the matching ones from merge-recursive. We care a bit less there, since the hope is that it will eventually go away. But besides being the right thing to do in the meantime, it is necessary for t6406 to pass both with and without GIT_TEST_MERGE_ALGORITHM set (one of our CI jobs sets it to "recursive", which will use the merge-recursive.c code). An alternative would be to use "grep -i" in the test to check the message, but it's nice for the test suite to be be more exact (we'd notice if the capitalization fix regressed).
